Demon Lord: Just a Block PC requirements, FPS and best settings

Quick answer: can your PC run Demon Lord: Just a Block?

Difficulty profile: how hard is Demon Lord: Just a Block to run?

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

Across the 937 games we have modelled, Demon Lord: Just a Block lands on a demand score of 4, ahead of 0% of them. In plain terms it is a light game for graphics hardware.

Behind the number is the publisher minimum card, Integrated graphics (OpenGL 3.2 compatible), converted to an equivalent 1080p High workload. That makes the score comparable between games, though not exact for any single one.

What it means by card class

• RTX 5060, our example of an entry card, hits roughly 253 FPS at 1080p and 253 FPS at 1440p, so you will not need to tune much.
• An RTX 5080 (a high-end card) has more power than Demon Lord: Just a Block can use, landing near 253 FPS at 1080p and 253 FPS at 1440p.
• With a mid-range card such as the RTX 5070 the game is limited by its engine long before the card, with roughly 253 FPS at 1080p and 253 FPS at 1440p according to our model.
• An RTX 5090 (an enthusiast card) has more power than Demon Lord: Just a Block can use, landing near 253 FPS at 1080p and 253 FPS at 1440p.

On the CPU side, Demon Lord: Just a Block scores 32, ahead of 47% of the 937 modelled games.

System requirements for Demon Lord: Just a Block

Official minimum and recommended specs for Demon Lord: Just a Block, translated into frame rates.

Taken from the Steam store page; developers can revise these with updates.

What the requirements mean in practice

The minimum card, Integrated graphics (OpenGL 3.2 compatible), is the floor Steam sets. In our model it hits roughly 147 FPS at 1080p on Low settings, and 81 FPS if you push it to High.

There is no recommended spec on the Steam page, which means the demand score for Demon Lord: Just a Block is anchored to the minimum card. Read the frame rates as a modelled guide.

You will need 1 GB RAM of RAM at minimum or 1 GB RAM to match the recommended spec, plus 500 MB available space on your drive.

What graphics card does Demon Lord: Just a Block need?

The lowest GPU we tested that delivers each target in Demon Lord: Just a Block, plus the first desktop RTX 50 card that does.

Start at the GTX 1060 6GB if you want 60 FPS at 1080p on High. Among current RTX 50 cards, the RTX 5050 is the first to manage it.

Raise the target to 1440p and the bar moves: the GTX 1060 6GB is the lowest card to reach 60 FPS on High, while the RTX 5050 is the first RTX 50 card to get there.

4K is the hard case. With Quality DLSS, FSR or XeSS-style upscaling enabled, the RTX 5050 is where the RTX 50 range first delivers 60 FPS on High.

NVIDIA, AMD and Intel cards all appear in the list. To test your own parts, open the can my PC run it checker, or see whether your processor limits you in the bottleneck checker.

Estimated Demon Lord: Just a Block FPS on 28 graphics cards

Modelled FPS for 28 graphics cards from NVIDIA, AMD and Intel. Pick a resolution to redraw the bars.

Top to bottom, the RTX 5090 averages roughly 253 FPS at 1440p (253 FPS at 4K) against 253 FPS for the RTX 5050 at 1440p. Where you land depends on the card and resolution you choose.

Full results table

Every figure assumes High settings and a fast processor. The two upscaled columns switch on Quality DLSS, FSR or XeSS-style upscaling, which only applies if the game supports it. Figures above 360 FPS are shown as 360+. Put two cards side by side in the GPU comparison tool.

Card by card verdicts for Demon Lord: Just a Block

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 according to our model.

The step from an RTX 5060 (253 FPS at 1440p) to an RTX 5070 (253 FPS) is roughly 0% according to our model, a useful yardstick when choosing between the two.

Best Demon Lord: Just a Block settings at 1080p, 1440p and 4K

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

1080p playbook

Native 1080p works on GTX 1660 Super, RTX 3060 12GB, RTX 4060, all above 60 FPS on High according to our model. Upscaling then becomes optional rather than required.

Pick your card in the table for the preset and DLSS, FSR or XeSS-style upscaling mode that keep 1080p above 60 FPS.

1440p playbook

Native 1440p works on RTX 4060, RTX 5060, RTX 5070, all above 60 FPS on High according to our model. Upscaling then becomes optional rather than required.

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

At 4K, RTX 5070 Ti, RTX 4080 Super, RTX 5080 hold 60 FPS natively on High according to our model, so you can leave DLSS, FSR or XeSS-style upscaling off and spend the headroom on settings.

Each row below is the best-looking combination that still holds 60 FPS at 4K according to our model.

Stepping up the RTX 50 range in Demon Lord: Just a Block

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

Our model finds the best value step at RTX 5050 to RTX 5060, roughly 0% faster at 1440p, and the weakest at RTX 5050 to RTX 5060, roughly 0%.

Do not overspend for Demon Lord: Just a Block. Past the mid-range the extra graphics power goes unused, and a better processor would help more.

Demon Lord: Just a Block VRAM requirements

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

We put Demon Lord: Just a Block at roughly 2 GB at 1080p High, 2.6 GB at 1440p and 3.6 GB at 4K. That is an estimate derived from the recommended GPU, so treat it as a guide and leave some memory spare.

If memory is tight, lower textures first: Medium brings the 1440p figure down to roughly 2.2 GB.

Budget tiers: 6, 8, 12 and 16 GB cards

• A 6 GB card is comfortable at 1080p, comfortable at 1440p and comfortable at 4K on High. Where it is short, Medium textures and DLSS, FSR or XeSS-style upscaling are the practical fixes.
• An 8 GB card is comfortable at 1080p, comfortable at 1440p and comfortable at 4K on High. Where it is short, Medium textures and DLSS, FSR or XeSS-style 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.

Demon Lord: Just a Block CPU requirements

What a range of popular CPUs can feed a graphics card here.

Steam gives Dual Core CPU as the minimum processor and Dual Core CPU as the recommended one. The table shows the most frames each chip can prepare according to our model, regardless of graphics settings.

Demon Lord: Just a Block is a mid-weight game for processors, ahead of 47% of those we model, so a recent mid-range chip is a sound match.

Use the Core i5-12400F as a yardstick: it feeds roughly 139 FPS here, so any card faster than that will be waiting on the processor.

Check your own CPU and GPU together in the bottleneck checker and our system bottlenecks guide.

Which builds are balanced in Demon Lord: Just a Block?

How seven common processor and graphics card pairs behave in this game.

Demon Lord: Just a Block leaves the processor as the limit in 7 of the seven pairings below. Take the RTX 4060 and Core i3-12100F: the CPU tops out around 106 FPS, below the roughly 360+ FPS the card could deliver at 1440p.

The best-balanced pairing is the RTX 5090 with Ryzen 7 9800X3D: its processor ceiling (roughly 291 FPS) sits close to what the card can draw (roughly 360+ FPS) at 1440p, so neither part is wasted.

Best settings for Demon Lord: Just a Block

A starting point for several popular cards. Cells list the highest-quality preset that keeps 60 FPS.

Read each cell as a recommended starting point for Demon Lord: Just a Block: the preset first, then the DLSS, FSR or XeSS-style upscaling mode and the estimated result.

• Then trim the costliest options. If the menu has shadows, fog or draw distance options, those are the usual culprits.
• Use DLSS, FSR or XeSS-style upscaling first. It gives up little detail for a large frame-rate gain. Take the gentlest mode that hits the frame rate you want.
• Keep textures high if you have the VRAM. They barely touch frame rate. This game is estimated at 2.6 GB for 1440p.
• Set a frame cap to match your display and keep the PC cooler, then use the VRR and frame cap calculator to pick the figure.
• Adjust a single setting at once 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. Get a personal recommendation in the best settings generator and compare DLSS, FSR or XeSS-style upscaling modes in the DLSS and frame generation estimator.

Laptop performance in Demon Lord: Just a Block

Modelled laptop results at the power limits laptops usually ship with.

For a gaming laptop, our estimates show RTX 5050 Laptop, RTX 5060 Laptop, RTX 5070 Laptop, RTX 5070 Ti Laptop, RTX 5080 Laptop, RTX 5090 Laptop hitting 60 FPS at 1080p on High at typical power.

Genre tips: playing Demon Lord: Just a Block well on PC

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

Steam lists Demon Lord: Just a Block under Action, Adventure, Casual, so these general tips apply. They are hedged guidance rather than facts about the game's engine.

• Role-playing games often run long sessions, so keep an eye on temperatures and memory use after a few hours.
• Casual games rarely stress a graphics card, so power and noise settings may matter more than raw speed.
• Indie games vary widely in how well they are optimised, so patch notes and community reports can say more than hardware specs.
• Large unit counts and busy maps can push processor use up late in a session, so a quick CPU helps more than a faster graphics card in many strategy games.
• Exploration games stream assets as you move, so storage speed and spare VRAM help avoid hitches when you enter new areas.
• Controller support makes living-room play practical, and TVs often cap at 60 or 120 Hz.

Steam features

The facts above are from the public Steam store page. We have not tested the game on every card, so frame rates on this page are modelled estimates.

Method: where the Demon Lord: Just a Block numbers come from

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

Here is what feeds the estimates: demand 4 from the minimum card, CPU score 32 (from an assumed processor line), and a 1080p High VRAM figure of 2 GB (estimated from the demand score).

Frame rates scale each graphics card against that demand, then adjust for resolution, preset, DLSS, FSR or XeSS-style upscaling and a memory penalty when a card runs short of VRAM. CPU limits cap the result using a fast reference processor in the GPU tables.

These are modelled estimates, not benchmarks. Real results change with drivers, patches, cooling, the scene you play and your processor. Use the numbers to compare cards and settings, then check them in the game.
