Rust

Rust has been one of the more demanding survival games on PC since its 2018 release, and pairing it with an Intel Core i5-12400F and an NVIDIA GeForce RTX 3070 Ti produces measured results that clear the 60 FPS bar at every resolution — as long as the settings are chosen sensibly. The data shows a combo that ranks 1294th out of 3723 tested hardware pairings for this game, comfortably in the upper half, with the RTX 3070 Ti sitting in the 75th percentile of all GPUs and the i5-12400F in the 73rd percentile of all CPUs. The short version: 1080p is fully unlocked at Ultra, 1440p plays best at High, and 4K demands a drop to Low. What follows is the full breakdown of where the frame rates land and why.

Best Settings per Resolution

At 1920x1080, the answer is simple: Ultra. The pairing averages 84 FPS at the maximum preset, a 24-frame cushion above the 60 FPS playability threshold. Nothing needs to be sacrificed.

At 2560x1440, the most demanding preset that stays at or above 60 FPS is High, delivering an average of 78.4 FPS. Stepping up to Ultra drops the average to 58.6 FPS — just under the line — so High is the correct ceiling at this resolution.

At 3840x2160, only one preset qualifies: Low, at an average of 81.1 FPS. Medium falls short at 54.7 FPS, and Ultra slides to 36.6 FPS. 4K is therefore playable, but only with visual detail stripped back considerably.

CPU and GPU Roles

The scaling data tells a clear story: Rust on this combo is GPU-bound at every resolution. Moving from 1080p to 1440p at Ultra costs 25.4 FPS (84 down to 58.6), and pushing to 4K Ultra nearly halves performance again to 36.6 FPS. That steep, monotonic decline as pixel count rises is the signature of a graphics card hitting its ceiling, not a CPU running out of thread throughput.

The CPU-side evidence supports this. The i5-12400F carries strong per-core credentials — a Cinebench R23 single-core score of 1680, a Geekbench single-core score of 1964, and a 3DMark single-thread score of 909 — which matters for Rust's frame pacing in populated server scenarios. But the preset-to-preset scaling at fixed resolution is what isolates the GPU: at 1080p, going from Low (196.6 FPS) to Ultra (84 FPS) cuts the frame rate by more than half while the CPU workload stays essentially constant. If the processor were the limiter, that gap would compress. It doesn't.

Practically, that means upgrades to visuals or resolution on this rig are gated by the RTX 3070 Ti's 8 GB of GDDR6X and its 608.3 GB/s of memory bandwidth, while the six-core, twelve-thread Alder Lake CPU sits with headroom in reserve.

Measured FPS Breakdown

All figures below are measured averages; minimum and maximum frame rates were not captured in this dataset.

1920x1080:

• Low: 196.6 FPS
• Medium: 129.6 FPS
• High: 112.9 FPS
• Ultra: 84 FPS

Every preset clears 60 FPS at 1080p, and even Ultra holds a 40% margin over the threshold. The Low preset's 196.6 FPS makes this pairing a legitimate option for high-refresh 1080p displays.

2560x1440:

• Low: 131.4 FPS
• Medium: 90.6 FPS
• High: 78.4 FPS
• Ultra: 58.6 FPS

Three of four presets are playable. Ultra misses by a single-and-a-half frames, which suggests that minor in-game tweaks beyond the preset slider could close the gap, but on the raw numbers it does not qualify. High at 78.4 FPS is the sweet spot — detail largely intact, frame rate comfortably above 60.

3840x2160:

• Low: 81.1 FPS
• Medium: 54.7 FPS
• High: 44.7 FPS
• Ultra: 36.6 FPS

Only Low survives at 4K. The drop from Low to Medium alone costs 26.4 FPS, and from Medium to High another 10 FPS — a total collapse of 44.5 FPS between the two extremes of the preset range. The 8 GB framebuffer on the RTX 3070 Ti is being asked to move 4K pixel loads, and the data shows where it gives out.

The Verdict

Yes — this PC runs Rust at every mainstream resolution. The verdict data is unambiguous:

• 1920x1080: Playable at all four presets (High, Low, Medium, Ultra). Best settings: Ultra, at 84 FPS average.
• 2560x1440: Playable at High, Low, and Medium. Best settings: High, at 78.4 FPS average.
• 3840x2160: Playable at Low only. Best settings: Low, at 81.1 FPS average.

For most players, 1440p at High is the ideal operating point: a 78.4 FPS average with most visual detail preserved. Players chasing high refresh rates should stay at 1080p, where even the Medium preset delivers 129.6 FPS. 4K is technically viable but only after significant visual compromise, so it is better treated as an occasional option than the default configuration. Ranked 1294 of 3723 combinations for this game, this pairing sits in the top half of tested hardware and behaves like a competent mid-to-upper-tier gaming build for Rust.

Similar Performance Alternatives

On the GPU side, the RTX 3070 Ti's rivals define a tight performance cluster. The AMD Radeon RX 6800 scores 30095 against the 3070 Ti's 29945 average benchmark score — a 0.5% gap — so Rust performance should be near-identical. The NVIDIA GeForce RTX 2080 Ti sits 0.5% below, the NVIDIA GeForce RTX 5070 Mobile is effectively even at a 0.1% delta, and the AMD Radeon RX 6700 is a mere 1.6% ahead. Any of these cards would reproduce the frame-rate table above within a small margin.

On the CPU side, the i5-12400F's rival list is similarly compressed. The AMD Ryzen 5 7535HS posts an average score of 19047 against the i5-12400F's 19039 — a dead heat at 0% delta. The Intel Core 3 201E is 0.1% off the pace, the Intel Core i5-1335U is 0.3% behind, and even the AMD EPYC 7773X lands within 0.3% on aggregate score. Given that Rust on this combo is GPU-bound at all three resolutions, any of these processors paired with a comparable GPU would deliver much the same experience.

FAQ

Q: Can the RTX 3070 Ti + i5-12400F run Rust at 4K?

A: Yes, but only at the Low preset, which averages 81.1 FPS. Medium (54.7 FPS), High (44.7 FPS), and Ultra (36.6 FPS) all fall short of the 60 FPS threshold.

Q: What is the best settings combination at 1440p?

A: High, averaging 78.4 FPS. It is the most demanding preset that stays at or above 60 FPS at 2560x1440; Ultra averages 58.6 FPS and misses the cutoff.

Q: Can this setup run Rust at Ultra settings?

A: At 1920x1080, yes — Ultra averages 84 FPS. At 1440p and 4K, no preset above High and Low respectively clears 60 FPS.

Q: Is Rust CPU-heavy or GPU-heavy on this configuration?

A: GPU-heavy. Frame rates fall steeply as resolution rises (84 FPS at 1080p Ultra versus 36.6 FPS at 4K Ultra) while the i5-12400F's strong single-core scores indicate spare processor headroom.

Q: How does the i5-12400F compare to rival CPUs?

A: Its average benchmark score of 19039 is statistically tied with the AMD Ryzen 5 7535HS (19047, 0% delta), Intel Core 3 201E (19056, 0.1% delta), and Intel Core i5-1335U (18982, 0.3% delta).

Q: Would a different GPU in the same class change the results much?

A: No. The Radeon RX 6800, RTX 2080 Ti, RTX 5070 Mobile, and RX 6700 all sit within roughly 1.6% of the RTX 3070 Ti's average benchmark score, so Rust frame rates would be very similar.
