What do you need before you start?
A few basics decide whether DLSS is possible, and checking them first saves time.
An RTX graphics card
DLSS needs the Tensor cores found on RTX cards. GTX cards cannot run it, as the guide to GTX versus RTX explains. Any RTX card from the 20 series upwards supports Super Resolution, while frame generation needs an RTX 40 or 50 series card.
How to check your card
Open the NVIDIA App or Windows Task Manager and look at the GPU name. If it begins with GeForce RTX, you are ready. If it begins with GTX, DLSS is not available.
A current driver
New DLSS versions and overrides arrive through drivers and the NVIDIA App. Update both before you begin. The site's guides to Game Ready and Studio drivers and updating drivers walk through the process.
A game that includes DLSS
The game must ship with the DLSS software. Many popular titles do, and the list grows each year. NVIDIA publishes lists of supported games, and the game's store page or settings menu will tell you as well.
Method one: enable DLSS in the game menu
This is the easiest route, and it works for most players.
Step by step
Start the game and open the settings. Go to the graphics or display section. Look for DLSS, NVIDIA DLSS or Super Resolution. Choose a mode, usually Quality, Balanced or Performance. Apply the change, and watch the frame rate.
Where the option hides
Some games place the option under an "upscaling" heading with several choices, such as DLSS, FSR and XeSS. Others put it next to the resolution setting. If you cannot find it, check the game's help page.
What the first test should be
Start with Quality, which gives the smallest picture change and a useful boost. The guide to DLSS quality, balanced and performance modes explains the modes.
Turn on the companion features
If the game offers Frame Generation or Reflex, you will find them near the DLSS option. Reflex reduces delay and is worth enabling in most games. Frame generation needs an RTX 40 or 50 series card and a healthy base frame rate. The DLSS 4 overview explains each feature.
Method two: use the NVIDIA App override
The override is the tool for games that lack an option, or that use an older DLSS.
What the override can and cannot do
It can switch a game to a newer DLSS model, enable DLAA or Ultra Performance in games that lack them, and set frame generation multipliers on supported RTX 50 series cards. It cannot add DLSS to a game that never included it, and it only works while DLSS is switched on inside the game.
Step by step
Open the NVIDIA App, go to Graphics and select Program settings. Choose your game from the list. Scroll to the Driver settings section. You will see DLSS Override options for Frame Generation, Model Presets and Super Resolution, depending on the game and your card. Choose the settings you want, and restart the game.
If the game is not listed
Run the game once, then check again, or add it manually using the app's option to add a program. Some games appear only after they have been launched.
How to confirm it worked
Use the NVIDIA overlay to turn on the DLSS indicator. It displays the DLSS version, preset and render resolution. If the details match your settings, the override is active.
Reverting an override
Set the option back to "Use the 3D application setting". Nothing permanent changes in the game files, which makes the override safer than manual file edits, covered in the DLL swap guide.
Which override option does what?
The app offers several choices, and a table clarifies them. Labels may vary slightly between app versions.
| Override | What it controls | When to use it |
|---|---|---|
| Super Resolution mode | Internal render resolution, including DLAA and Ultra Performance | When a game lacks a mode you want |
| Model presets | Which AI model rebuilds the picture | To try newer models in older games |
| Frame Generation | Multiplier and model for generated frames | On supported cards, with healthy base frame rate |
Using the table
Change one override at a time, and restart after each. Our guides on presets and Multi Frame Generation explain the choices in detail.
Fixes when the option is greyed out or missing
Most problems have simple causes.
The game does not support DLSS
This is the commonest reason. Check the game's store page or NVIDIA's list. If the game has no DLSS, no setting will add it.
DLSS is off inside the game
An override applies only if DLSS is switched on in the game. Enable it first, then restart.
Conflicting display settings
Some games disable DLSS in certain display modes or when another upscaler is chosen. Try borderless or fullscreen mode, and select DLSS explicitly instead of an automatic option.
Old driver or app
Update the NVIDIA App and the graphics driver. Missing options often return after an update.
Windows and hardware settings
Make sure the game runs on your RTX card, not on integrated graphics. Laptop owners should check the graphics preference in Windows settings.
A full walkthrough: from fresh install to tuned settings
This worked example takes you through a typical session. It is an illustration, and your menus may look different.
Step one: update everything
Install the latest Game Ready driver, or the Studio driver if you prefer it, and update the NVIDIA App. Restart the computer. These steps remove many mysterious problems before they appear.
Why a restart matters
Drivers and apps load components at startup. A restart makes sure the new versions are in use, not the old ones.
Step two: set up Windows
Open Windows display settings and confirm your monitor's resolution and refresh rate. Many players discover their monitor is running at 60 Hz because Windows chose a default. The article on running a 4K display at its native resolution and maximum refresh rate explains the fix.
Step three: start the game and enable DLSS
Open the game's graphics settings, switch on DLSS Super Resolution and choose Quality. Enable Reflex if available. Apply the changes, and play for a few minutes.
Step four: check with the indicator
Open the NVIDIA overlay and enable the DLSS indicator. Confirm that the DLSS version is recent and that the render resolution matches the mode you chose.
What if the version is old?
Use the NVIDIA App override to choose the latest model preset, restart the game and check again.
Step five: tune
If the frame rate falls short, move one mode lighter. If the picture looks soft, try a newer preset or a higher mode. Make one change at a time and write down what you did.
Common questions about using overrides well
Should I set overrides globally or per game?
The app offers global and per-game settings. Per-game settings are safer, because a global override can behave differently across games. Use global settings only when you are sure they suit everything you play.
Do overrides affect performance?
They change what DLSS does, so they can change performance. A newer model may cost a few frames. A lower mode raises the frame rate. Measure in your own game.
Can I use the override with other upscalers?
No. DLSS, FSR and XeSS are separate choices. Select one in the game, and avoid stacking others on top.
What about older cards?
RTX 20 and 30 series cards can use the override for Super Resolution and model presets. Frame generation options require newer cards.
Setting up different games with different needs
Game types call for different choices.
Single-player adventures
Use Quality or Balanced, enable Reflex, and consider frame generation on an RTX 40 or 50 card if the base frame rate is healthy. Prioritise picture quality.
Competitive shooters
Use the lightest settings that give a high, steady frame rate, enable Reflex, and avoid frame generation unless you prefer the smoother picture. Prioritise delay.
Racing and flight games
Use Balanced or Quality, test for shimmering on road markings and thin lines, and pick a newer preset if you see it.
Strategy and simulation games
DLSS adds little at modest resolutions. Use it if the game is heavy, or switch to DLAA for the cleanest picture on a powerful card.
Keep profiles
Create a profile for each game type in the NVIDIA App, so you do not need to adjust settings every time you launch something different.
Special cases that trip people up
A few setups behave differently, and knowing them saves frustration.
Laptops with two graphics chips
Many laptops have an integrated chip and an RTX chip, and Windows decides which one a game uses. If DLSS options are missing, the game may be running on the integrated chip. Open Windows graphics settings, add the game and set it to use the high-performance GPU. The NVIDIA App also lets you choose the processor for each program.
How to check
Open Task Manager during the game and look at which GPU shows activity. If the RTX chip sits idle, the game is on the wrong chip.
Desktops with a monitor plugged into the wrong port
If you plug your monitor into the motherboard instead of the graphics card, Windows may use the processor's built-in graphics. The game then runs poorly, and DLSS may be unavailable. Always connect the monitor to the graphics card's ports.
Games launched through other launchers
Some games start through a launcher that applies its own settings. If overrides do not appear to work, try launching the game directly, or make sure the NVIDIA App has the right executable listed.
Games that update their files
When a game updates, it may replace its DLSS file with a different version. Recheck your override after large patches.
Using the frame generation override in detail
The frame generation override is the most powerful and the most easily misused option.
Before you touch it
Enable frame generation inside the game, check that Reflex is on and make sure your base frame rate is comfortable. The override does not work if the in-game setting is off. Our guide to Multi Frame Generation explains why a healthy base matters.
Setting the multiplier
Exit to the desktop, open the NVIDIA App and find the game under Program settings. Under Driver settings, choose the Frame Generation override and pick a multiplier. NVIDIA has suggested a multiplier of 3x if you are aiming for about 180 frames per second and 4x for 240 or more, on supported RTX 50 cards. Restart the game afterwards.
What about dynamic modes?
NVIDIA's DLSS 4.5 update introduced dynamic and higher multiplier modes for RTX 50 cards, set through the app's override. If your app shows them, you can try a target frame rate equal to your monitor's refresh rate. Availability depends on your card, driver and app version.
Testing the result
Play for ten minutes, and check both the smoothness and the feel of the controls. If the game feels heavy, lower the multiplier or switch frame generation off.
Games with more than one upscaler
Modern games often list several upscalers, and choosing the right one matters.
How to pick DLSS in a list
Select DLSS explicitly, not an automatic or default option. Some games choose FSR by default, even on NVIDIA cards.
Why not use several at once
Stacking upscalers or sharpening filters can cause strange visuals. Use one upscaler, and turn off extra sharpening until you have judged the result. The comparison of DLSS, FSR and XeSS explains the differences.
Interface scaling
Some games have an option to apply upscaling to the interface. Leaving it off keeps text crisp. If text looks blurry, check the setting.
Four example players
These imaginary players show different routes to the same goal.
The beginner
This player installs the driver, opens the game and chooses Quality. The frame rate improves, they enable Reflex and they stop there. That is perfectly good.
The tinkerer
This player installs the NVIDIA App, tries the latest model preset in three games and keeps it in two. They note the settings for each.
The laptop owner
This player discovers the game was running on the wrong chip, fixes it in Windows settings and sees DLSS appear in the menu.
The 4K television player
This player uses Performance mode with the override for a newer model, sets a frame cap and enjoys smooth play from the sofa.
What they share
Each followed a short, logical routine, and none needed expert knowledge.
Common mistakes
Skipping the in-game switch
An override does nothing if DLSS is off in the game. Switch it on first.
Forgetting to restart
Many changes apply only on launch. Restart the game after every change.
Changing too many things
Change one setting at a time, so you know what caused any difference.
Trusting the menu over the indicator
Use the on-screen indicator to see what is really running.
Downloading tools from unofficial sites
Use NVIDIA's own app and website, and avoid unofficial downloads.
Global settings versus per-game settings
The NVIDIA App offers settings at two levels, and understanding both helps you stay organised.
Global settings
Global settings apply to every program that does not have its own entry. They suit options you always want, such as a preferred power mode. They are risky for DLSS overrides, because different games respond differently to the same choice.
Per-game settings
Per-game settings, found under Program settings, apply only to that game. They are the right place for DLSS overrides, because you can tune each game and keep the rest untouched. The site's guide to a sensible global NVIDIA Control Panel profile explains the global side.
Keeping tidy
Name your notes by game, record the date and list the overrides you set. If a game updates and misbehaves, you will know exactly what to change.
How DLSS settings relate to your monitor
DLSS is one part of a chain that ends at your monitor, and the chain works best when each link is set correctly.
Resolution and refresh rate
Set the monitor to its native resolution and highest refresh rate in Windows before you tune DLSS. A game running at the wrong resolution wastes both performance and picture quality.
Variable refresh rate
If your monitor supports variable refresh rate, enable it. It lets the screen match the frame rate, which hides small dips. The article on VRR, G-Sync, FreeSync and V-Sync explains the options.
Frame caps
Cap the frame rate a few frames below the monitor's refresh rate if you use variable refresh rate. This keeps the display in its smooth range and reduces heat.
Cables and ports
A high refresh rate needs a suitable cable. If your monitor will not offer its top refresh rate, check the cable and the port before blaming the game.
What to do when a game updates
Game patches can change DLSS behaviour, and a quick routine keeps you in control.
Check your settings after the patch
Open the game and confirm that DLSS is still on, that the mode matches your choice and that the indicator shows the version you expect. Patches sometimes reset graphics options.
Retest overrides
If the patch added a newer DLSS version, your override may no longer be needed, or it may behave differently. Try the game with the override off and on.
Read the patch notes
Developers often list DLSS changes. A single line about an upgraded version can tell you why the picture looks different.
Reasons DLSS might look worse than expected
If DLSS disappoints, the cause is often simple.
The mode is too aggressive for your resolution
Performance mode at 1080p starts from a very small image, as explained in the guide to DLSS modes. Move up a mode.
Extra sharpening is applied
Some games add sharpening, and so do drivers. Remove extras, and judge DLSS alone.
An old model is in use
The game may ship with an early version. Try the latest model through the app.
Motion blur or film grain interfere
These post-processing effects can mask or exaggerate artefacts. Turn them off while you compare.
Your monitor is the bottleneck
A slow panel can smear motion, which looks like ghosting. Check your monitor's response settings.
Extra tips from experienced players
A few habits make life easier over the long run.
Test in the same place every time
Choose a spot in the game with plenty of detail, and use it for every comparison. Consistent test conditions make small differences visible, and they stop you chasing changes that come only from the scene.
Use the lightest settings that please you
It is tempting to chase the highest quality mode. In practice, the lightest mode that looks good to you gives the best experience, because it leaves headroom for busy scenes and keeps the card cooler and quieter.
Take screenshots of your settings
A quick screenshot of the in-game menu and the NVIDIA App page costs seconds and can save an evening if an update resets something.
Share settings with care
If you copy settings from someone else, remember that their card, monitor and tastes differ from yours. Treat shared settings as a starting point.
Learn one feature at a time
You do not need to master upscaling, frame generation, presets and Reflex on the same evening. Start with Super Resolution, add Reflex, and explore the rest when you feel ready. The DLSS 4 overview is a good map for later.
Remember why you are tuning
The goal is a game that feels good, not a perfect score. If you find yourself comparing screenshots for an hour, stop, play for a while and see whether anything bothers you. Often the answer is nothing, and the time is better spent enjoying the game. When something does bother you, you now have a clear routine to follow, and every change can be undone in moments.
When you share a computer
If other people use your PC, create a separate Windows account for them or note which settings you changed. A cheerful family member who resets graphics options can undo your careful work, and a short note on the desk saves arguments. If you play on a shared household computer, keep your preferred settings written down so you can restore them in a minute after anyone else has used it.
Keep an eye on future updates
NVIDIA adds options to the app regularly, and menu labels can change. If a screen in this guide does not match what you see, look for the same idea under a similar name, and check NVIDIA's release notes. The principles stay the same even when the buttons move.
Summary and next steps
Enabling DLSS is straightforward: you need an RTX card, a current driver and a game that includes the feature. Switch it on in the game's menu, start with Quality and check the frame rate. If the game offers no option or uses an old version, the NVIDIA App's override can apply newer models and extra modes without editing files, as long as DLSS is switched on in the game first. Use the on-screen indicator to confirm what is running, change one setting at a time and restart the game after each change. Keep notes, recheck after updates and revert any change that does not help. For deeper control, read about presets, Ray Reconstruction and the NVIDIA App. With a little care, you will find a setup that looks good and plays smoothly.
Quick start checklist
- Confirm you have an RTX card.
- Update the driver and the NVIDIA App.
- Connect the monitor to the graphics card.
- Enable DLSS Super Resolution in the game, starting at Quality.
- Turn on Reflex.
- Turn on the DLSS indicator to confirm.
- Adjust one setting at a time, and note what works.
Troubleshooting table
| Symptom | Likely cause | What to try |
|---|---|---|
| DLSS missing from menu | Game lacks DLSS | Check supported list, try FSR or XeSS if offered |
| Override has no effect | DLSS off in game, or game not restarted | Enable DLSS in game, restart |
| Picture looks worse after override | Game tuned for the old model | Revert the override |
| Frame rate falls | Heavier model or mode | Use a faster mode or the first transformer preset |
| Game crashes at launch | Incompatible setting | Revert overrides, update drivers |
| Indicator not visible | Overlay disabled | Enable the overlay and indicator in the app |
A habit that saves time
Take a screenshot of your NVIDIA App settings for each game. If something goes wrong after an update, you can restore your known good setup in a minute.
Safety and fair play
Settings changes are safe, but a few notes are worth knowing.
Anti-cheat and online games
Overrides work through the driver, which is designed to be safe. Still, if a game's rules are strict, check them before experimenting. Modified game files are riskier, and the guide to DLL swapping explains why.
Official sources only
Download drivers and the NVIDIA App from NVIDIA. Avoid unofficial tools that promise to unlock features, because they may carry malware or break your game.
Keep a backup of working settings
Note your resolution, refresh rate, DLSS mode, preset and frame generation settings for each game. It takes a minute and protects you from surprise changes.

Frequently asked questions about enabling DLSS
How do I turn on DLSS in a game?
Open the game's graphics settings and look for DLSS, NVIDIA DLSS or Super Resolution. Choose a mode such as Quality, apply it and check your frame rate. You need an RTX graphics card, a current driver and a game that includes DLSS. If the option is missing, the game may not support it.
Can I force DLSS in a game that does not support it?
No. The NVIDIA App override can change the version or mode of DLSS in games that already include it, but it cannot add DLSS to a game that does not. For unsupported games, you may be able to use other upscalers such as FSR or XeSS, if the game offers them.
Why is the DLSS option greyed out?
Common causes include a game that does not support DLSS, a display mode that conflicts with it, an outdated driver, or running the game on the wrong graphics chip. Try borderless or fullscreen mode, update the driver, and confirm that the game is using your RTX card.
Is the NVIDIA App override safe?
Yes. It works at the driver level and does not edit game files, and you can revert it at any time by choosing to use the application's setting. Some online games with strict anti-cheat rules may restrict changes, so check the game's rules if you play competitively.
Do I need the NVIDIA App to use DLSS?
No. DLSS works from the game's own menu with only a driver installed. The NVIDIA App adds convenience and overrides for newer models and modes. Most players find it useful, and it is free, but you can enable DLSS in games without it.
How can I check that DLSS is really on?
Turn on the DLSS indicator in the NVIDIA overlay. It shows the DLSS version, preset and render resolution on screen while you play. If it displays details, DLSS is active. If it shows nothing, check that the game's DLSS setting is enabled and restart.
