SubZero PC requirements, FPS and best settings

SubZero on PC: the quick answer

Difficulty profile: how hard is SubZero to run?

How this game ranks among 937 modelled titles, and what that means for different classes of graphics card.

With a demand score of 7, SubZero asks more of a graphics card than 28% of the 937 games in our list. We call that undemanding.

It comes from the recommended card on the Steam page (GTX 1050 or better), 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

• On a mid-range card, the RTX 5070, expect the frame rate to be capped by the game or CPU: roughly 253 FPS at 1080p, 253 FPS at 1440p.
• RTX 5080, our example of a high-end card, hits close to 253 FPS at 1080p and 253 FPS at 1440p, so you will not need to tune much.
• With an enthusiast card such as the RTX 5090 the game is limited by its engine long before the card, with close to 253 FPS at 1080p and 253 FPS at 1440p by our model.
• On an entry card, the RTX 5060, expect the frame rate to be capped by the game or CPU: roughly 253 FPS at 1080p, 253 FPS at 1440p.

On the CPU side, SubZero scores 32, ahead of 47% of the 937 modelled games.

SubZero PC requirements: minimum and recommended

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

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

How the published specs translate to frame rates

At the bottom end, Steam lists GTX 1050 or better. That card manages roughly 140 FPS at 1080p on Low by our estimates, falling to close to 77 FPS on High.

Step up to the recommended GTX 1050 or better and the model returns roughly 77 FPS at 1080p and 50 FPS at 1440p. That is above 60 FPS at 1080p, so the recommended spec reads as a comfortable 1080p target.

Steam sets memory at 4 GB RAM minimum, 4 GB RAM recommended, and asks for 20 GB available space of storage.

Best graphics card for SubZero by target

Pick a target and see the card it needs in SubZero.

Our estimates put 1080p 60 FPS on High within reach of the GTX 1060 6GB and above, with the RTX 5050 as the cheapest RTX 50 route there.

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

For 4K, DLSS, FSR or XeSS-style upscaling does most of the work: with Quality upscaling the RTX 5050 is the first RTX 50 card to achieve 60 FPS on High.

Cards across NVIDIA, AMD and Intel are included. Add your own processor, memory and settings in the can my PC run it checker and check for a processor limit in the bottleneck checker.

SubZero FPS by graphics card

Estimated frame rates for 28 graphics cards from NVIDIA, AMD and Intel. Use the buttons to change resolution.

Top to bottom, the RTX 5090 averages close to 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

All numbers are for 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. Results over 360 FPS appear as 360+. Compare two cards directly in the GPU comparison tool.

Is your graphics card good enough for SubZero?

Twelve popular cards, with a plain-English verdict for each.

Think of the verdict column as a starting point. It judges every card with High settings, so a modest result can often be improved by dropping one preset or using DLSS, FSR or XeSS-style upscaling.

Between the RTX 5060 (253 FPS at 1440p) and the RTX 5070 (253 FPS) there is roughly a 0% difference in SubZero.

Resolution playbook for SubZero: 1080p, 1440p and 4K

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 by our estimates, which leaves room to raise individual settings.

Each row below is the best-looking combination that still holds 60 FPS at 1080p by our model.

1440p playbook

For 1440p play, RTX 4060, RTX 5060, RTX 5070 clear 60 FPS on High without any DLSS, FSR or XeSS-style upscaling by our estimates, which leaves room to raise individual settings.

Start from the preset that still reaches 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 by 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 by our model.

Is a graphics card upgrade worth it for SubZero?

What each step up the RTX 50 range adds at 1440p with High settings.

Of the six steps up the RTX 50 range, RTX 5050 to RTX 5060 gives the most in SubZero (close to 0% at 1440p), while RTX 5050 to RTX 5060 gives the least (close to 0%).

Because SubZero is light on graphics hardware, upgrades beyond the middle of the range mostly raise a number the game or CPU already limits, so a dearer card buys little.

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

Graphics memory for SubZero: how much is enough?

What the game is likely to want from graphics memory on High. Falling short of VRAM causes stutter even with a quick GPU.

Estimated graphics memory use is 2 GB at 1080p, 2.6 GB at 1440p and 3.6 GB at 4K with High settings. The figure is an estimate derived from the recommended graphics card.

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.
• On an 8 GB card, 1080p is comfortable, 1440p is comfortable and 4K is comfortable 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.
• A 16 GB card is comfortable at 1080p, comfortable at 1440p and comfortable at 4K on High. Memory is rarely a worry at these settings.

Check your own settings in the VRAM calculator and see how much VRAM you need for gaming.

Which processor do you need for SubZero?

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

Steam gives Intel Core i3 as the minimum processor and Intel Core i5 / AMD equivalent as the recommended one. The table shows the most frames each chip can prepare by our model, regardless of graphics settings.

The CPU load sits in the middle of our range for SubZero, which means a modern mid-range processor will not hold back a typical card.

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.

See whether your parts match in the bottleneck checker and read system bottlenecks guide.

CPU and GPU pairings for SubZero

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

Look for the Processor label below: 7 of the seven pairings carry it. With RTX 4060 and Core i3-12100F the chip caps frames near 106 FPS even though the card is good for close to 299 FPS.

If you want neither part to idle, RTX 5090 with Ryzen 7 9800X3D comes closest at 1440p, with a CPU ceiling near 291 FPS and a card good for close to 360+ FPS.

Treat the builds as worked examples. Your own CPU and GPU can be tested together in the bottleneck checker.

SubZero memory and disk space

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

Memory first. Steam sets 4 GB RAM as the minimum and 4 GB RAM as the recommended amount. With Windows, a browser and a chat app open, 16 GB leaves comfortable headroom.

Free up close to 20 GB before you install. On a 100 Mbps connection the download is close to 31 min, and on 500 Mbps around 6 min.

Steam does not state an SSD requirement, so an SSD still improves loading times, but a hard drive should not stop the game launching.

Size your memory with the RAM calculator, which counts Windows, background apps and streaming on top of the game. Estimate the wait with the download time calculator.

Best settings for SubZero

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

The table gives the best-looking setup that still holds 60 FPS in SubZero for each card and resolution.

• Keep textures high if you have the VRAM. The speed cost is small. The model puts this game at 2.6 GB at 1440p.
• Reach for DLSS, FSR or XeSS-style upscaling first. You lose little sharpness and gain a lot of speed. Take the gentlest mode that hits the frame rate you want.
• Then trim the costliest options. If the menu has shadows, fog or draw distance options, those are the usual culprits.
• Change one thing at a time and note the effect on FPS before moving on.
• Limit the frame rate to your monitor to save power and heat, and the VRR and frame cap calculator suggests a sensible number.

These tables assume the game includes an upscaler, so look in its graphics menu. For advice matched to your own PC, use the best settings generator or compare every mode in the DLSS and frame generation estimator.

Laptop performance in SubZero

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 5050 Laptop, RTX 5060 Laptop, RTX 5070 Laptop, RTX 5070 Ti Laptop, RTX 5080 Laptop, RTX 5090 Laptop also holding 60 FPS at 1440p.

Laptop GPUs lose performance at lower power limits (TGP), and thin designs often cannot sustain them. Check the exact wattage of the model you are buying.

Game facts and Steam reviews for SubZero

On Steam the game sits at Very Positive: 92% positive across 2,722 reviews at the time of checking (2026-11-02). Larger communities tend to share more settings guides and fixes.

It was out for close to 6 months when we wrote this guide, so expect patches and driver updates to move the numbers a little over time.

Steam features

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

How we estimated SubZero performance

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

Three numbers drive this page: graphics demand 7 (from the recommended card), CPU score 32 (from an assumed processor line) and VRAM of 2 GB at 1080p High (estimated from the demand score).

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

All FPS, VRAM and CPU figures are modelled. They are meant for comparing hardware and settings, and your own testing should have the last word.
