SULFUR PC requirements, FPS and best settings

Can your PC run SULFUR? The short answer

Difficulty profile: how hard is SULFUR to run?

How this game ranks among 937 modelled titles, with a look at what that means for each class of card.

With a demand score of 28, SULFUR asks more of a graphics card than 80% of the 937 games in our list. We call that demanding.

It comes from the recommended card on the Steam page (GTX 1080 or equivalent), which we map onto a common performance scale and convert to 1080p High. Treat it as a relative guide.

What it means by card class

• For a high-end card we use the RTX 5080. It returns about 253 / 204 / 117 FPS at 1080p, 1440p and 4K on High. Native 4K works here at close to 117 FPS, with no DLSS, FSR or XeSS-style upscaling needed.
• As a mid-range card, the RTX 5070 manages 231 FPS at 1080p, 149 FPS at 1440p and 86 FPS at 4K. Reaches 86 FPS at 4K on High, so native 4K is realistic.
• As an enthusiast card, the RTX 5090 manages 253 FPS at 1080p, 253 FPS at 1440p and 186 FPS at 4K. Native 4K works here at about 186 FPS, with no DLSS, FSR or XeSS-style upscaling needed.
• Take an entry card, the RTX 5060: about 135 FPS at 1080p, 87 FPS at 1440p and 50 FPS at 4K on High. Treat 4K as an DLSS, FSR or XeSS-style upscaling job: 50 FPS native, 75 FPS upscaled.

For the processor we score SULFUR at 32, which is above 47% of our data set.

SULFUR system requirements

The official specs for SULFUR, compared with real graphics cards and processors.

Published by the developer on Steam and subject to change with patches.

How the published specs translate to frame rates

At the bottom end, The Steam page lists GTX 970 or equivalent. That card manages roughly 56 FPS at 1080p on Low on our figures, falling to close to 31 FPS on High.

Steam suggests GTX 1080 or equivalent as the recommended card, good for about 81 FPS at 1080p and 52 FPS at 1440p on High here. That is above 60 FPS at 1080p, so the recommended spec reads as a comfortable 1080p target.

Memory is listed as 8 GB RAM at minimum and 16 GB RAM recommended, with 4 GB available space needed on disk.

What graphics card does SULFUR need?

From a 30 FPS floor to 4K, here is the card each target asks for in SULFUR.

Start at the GTX 1660 Super if you want 60 FPS at 1080p on High. Among current RTX 50 cards, the RTX 5050 is the first to manage it.

At 1440p the entry card for 60 FPS on High is the RX 7600, with the RTX 5050 leading the RTX 50 line.

For 4K, DLSS, FSR or XeSS-style upscaling does most of the work: with Quality DLSS, FSR or XeSS-style upscaling the RTX 5060 is the first RTX 50 card to hit 60 FPS on High.

NVIDIA, AMD and Intel cards all appear in the list. Add your own processor, memory and settings in the can my PC run it checker, or see whether your processor limits you in the bottleneck checker.

SULFUR FPS by graphics card

Modelled FPS for 28 graphics cards from NVIDIA, AMD and Intel. Use the buttons to change resolution.

The fastest card here, the RTX 5090, returns around 253 FPS at 1440p and 186 FPS at 4K. The RTX 5050 sits at roughly 65 FPS at 1440p, which shows how wide the range is in SULFUR.

Full results table

These estimates use High settings and a fast processor. The two upscaled columns switch on Quality upscaling, which only applies if the game supports it. Anything over 360 FPS is capped at 360+ for display. Compare two cards directly in the GPU comparison tool.

Graphics card verdicts: how each one handles SULFUR

A verdict in plain English for twelve popular graphics cards.

Verdicts below use High settings throughout. For older cards a weak result mostly means lowering the preset, since Low and Medium settings recover a lot of speed in our modelling.

The step from an RTX 5060 (87 FPS at 1440p) to an RTX 5070 (149 FPS) is close to 71% in our modelling, a useful yardstick when choosing between the two.

SULFUR settings by resolution

Settings that hold 60 FPS at 1080p, 1440p and 4K, worked out for this game.

1080p playbook

For 1080p play, GTX 1660 Super, RTX 3060 12GB, RTX 4060 clear 60 FPS on High without any DLSS, FSR or XeSS-style upscaling on our figures, which leaves room to raise individual settings.

Use the table as a starting point: it shows the highest preset that still delivers 60 FPS for each card at 1080p.

1440p playbook

At 1440p, RTX 4060, RTX 5060, RTX 5070 hold 60 FPS natively on High in our modelling, so you can leave DLSS, FSR or XeSS-style upscaling off and spend the headroom on settings.

Start from the preset that still delivers 60 FPS, then raise one setting at a time. The table gives the best preset for each card.

4K playbook

For 4K play, RTX 5070 Ti, RTX 4080 Super, RTX 5080 clear 60 FPS on High without any DLSS, FSR or XeSS-style upscaling on our figures, which leaves room to raise individual settings.

Each row below is the best-looking combination that still holds 60 FPS at 4K in our modelling.

Stepping up the RTX 50 range in SULFUR

How much faster each next RTX 50 card is at 1440p on High settings.

The biggest single step in SULFUR is RTX 5060 Ti 16GB to RTX 5070, worth close to 43% at 1440p in our modelling. The smallest is RTX 5070 to RTX 5070 Ti at roughly 17%.

Treat the gains as a guide for value. Higher steps cost more per extra frame, so the sensible choice depends on the resolution and refresh rate you actually play at.

Compare options directly in the upgrade value calculator or the GPU price to performance calculator.

SULFUR VRAM requirements

Estimated graphics memory use on High settings. Too little VRAM hurts smoothness whatever the GPU speed.

We put SULFUR at about 4 GB at 1080p High, 5.2 GB at 1440p and 7.2 GB at 4K. That is an estimate derived from the recommended GPU, so treat it as a guide and leave some memory spare.

Texture settings have the biggest effect on VRAM. In our model Medium textures cut 1440p use from 5.2 GB to about 4.4 GB.

What each memory size means for SULFUR

• On a 6 GB card, 1080p is comfortable, 1440p is tight and 4K is short of memory on High. Where it is short, Medium textures and upscaling are the practical fixes.
• On an 8 GB card, 1080p is comfortable, 1440p is comfortable and 4K is tight on High. Where it is short, Medium textures and upscaling are the practical fixes.
• On a 12 GB card, 1080p is comfortable, 1440p is comfortable and 4K is comfortable on High. Memory is rarely a worry at these settings.
• On a 16 GB card, 1080p is comfortable, 1440p is comfortable and 4K is comfortable on High. Memory is rarely a worry at these settings.

SULFUR processor guide

How much frame rate each processor can prepare in this game.

The published CPU range runs from 2.4 GHZ Dual Core Processor to 2.4 GHZ Quad Core Processor. We turn that into a frame-rate ceiling for nine popular processors in the table.

Processor demand is moderate, at 47% of the way up our scale, so any recent six-core chip should cope.

A Core i5-12400F tops out near 139 FPS in SULFUR on our figures, a handy line to compare against your card.

Test your own pairing in the bottleneck checker and read system bottlenecks guide.

Which builds are balanced in SULFUR?

Does the CPU or the GPU set the pace? Seven example builds.

In 1 of the seven builds the processor, not the GPU, sets the 1440p frame rate in SULFUR. The first is the RTX 5090 with Ryzen 7 9800X3D, which the CPU holds near 291 FPS while the card could draw about 324.

The best-balanced pairing is the RTX 5090 with Ryzen 7 9800X3D: its processor ceiling (about 291 FPS) sits close to what the card can draw (close to 324 FPS) at 1440p, so neither part is wasted.

These pairings are examples, not recommendations to buy. Swap in your own parts with the bottleneck checker to see which side limits you.

SULFUR memory and disk space

RAM and disk space from the Steam page, with a practical view.

For RAM, expect 8 GB RAM at minimum and 16 GB RAM recommended. Allow for the operating system and background apps, which means 16 GB is a sensible floor.

Storage is listed at about 4 GB. Expect around 6 min to download on a 100 Mbps line, or roughly 1 min on 500 Mbps.

There is no SSD requirement on the page, but faster storage never hurts.

Add up your own needs in the RAM calculator, which adds your usual background apps to what the game asks for. Time the download with the download time calculator.

Recommended SULFUR settings by graphics card

Starter settings for six well-known cards. Each cell is the highest preset that still delivers 60 FPS.

These are our model's best 60 FPS setups for SULFUR, ranked by image quality.

• After that, cut the most expensive settings. If the menu has shadows, fog or draw distance options, those are the usual culprits.
• Limit the frame rate to your monitor to save power and heat, and check the VRR and frame cap calculator for a sensible figure.
• Leave textures on High when your card has the memory. They barely touch frame rate. This game is estimated at 5.2 GB at that resolution.
• Reach for upscaling first. It costs little image quality and gains many frames. Take the gentlest mode that reaches the frame rate you want.
• Change one thing at a time and watch the frame rate, so you know which setting did the work.

These tables assume the game includes an upscaler, so look in its graphics menu. Want a tailored answer? Open the best settings generator, or compare modes in the DLSS and frame generation estimator.

Can a gaming laptop run SULFUR?

What RTX 50 laptop GPUs manage at common wattages.

Among RTX 50 laptop GPUs, RTX 5050 Laptop, RTX 5060 Laptop, RTX 5070 Laptop, RTX 5070 Ti Laptop, RTX 5080 Laptop, RTX 5090 Laptop clear 60 FPS at 1080p on High at typical wattage, with RTX 5060 Laptop, RTX 5070 Laptop, RTX 5070 Ti Laptop, RTX 5080 Laptop, RTX 5090 Laptop also holding 60 FPS at 1440p.

Power limit matters on a laptop: the same GPU name can perform very differently at 60 W and 120 W, and cooling decides how long it holds the higher figure.

Tips for an Action/Adventure/Indie games like SULFUR

General guidance for this kind of game, chosen from the Steam genres and features.

These are general tips for demanding games of this type, not claims about how SULFUR itself is built. Use them as a prompt for what to test.

• Exploration games stream assets as you move, so storage speed and spare VRAM help avoid hitches when you enter new areas.
• Small teams sometimes skip advanced graphics menus, so resolution scaling and a frame cap may be your best tools.
• Open and large RPG worlds stream in data constantly, so an SSD and enough VRAM help keep movement smooth.
• Full controller support is listed, so playing from the sofa on a TV is an option, where 60 FPS is usually the sensible target.
• Simulation titles often build up complexity over hours of play, so test with a mature save rather than a fresh start.
• Fast action is easier to play with a steady frame rate than a high peak, so consider capping a few frames below your monitor refresh rate.

About SULFUR on PC

At the time we checked (2026-11-02) Steam showed 6,621 reviews with a Very Positive rating and 89% positive. That is a useful signal for how widely played SULFUR is.

It was out for about 1 month when we wrote this guide, so expect patches and driver updates to move the numbers a little over time.

Steam features

The facts above are from the public Steam store page. Frame rates here are modelled, since we have not tested the game on every card.

How the SULFUR estimates work

A short, honest note on how the numbers are produced.

Here is what feeds the estimates: demand 28 from the recommended card, CPU score 32 (from an assumed processor line), and a 1080p High VRAM figure of 4 GB (estimated from the demand score).

Each card is scored against the game demand, then scaled for resolution, quality preset and upscaling. If a card has less VRAM than the game wants, the estimate drops, and a processor ceiling stops frame rates running away.

Nothing on this page is a measured benchmark. Expect real frame rates to differ with drivers, updates and your own system, and treat the tables as a guide.
