Subnautica benchmark on RTX 3080 12GB: FPS by resolution and quality
Pick yours and we recalculate the whole table above with it.
Subnautica FPS with a RTX 3080 12GB and a Intel Core i5-13400
| Quality | 1080p (Full HD) | 1440p (2K) | 4K (Ultra HD) |
|---|---|---|---|
| Ultra | 367FPS min 177Excellent | 306FPS min 158Excellent | 176FPS min 111Excellent |
| High | 477FPS min 230Excellent | 397FPS min 205Excellent | 229FPS min 145Excellent |
| Medium | 500FPS min 241Excellent | 500FPS min 258Excellent | 299FPS min 189Excellent |
| Low | 500FPS min 241Excellent | 500FPS min 258Excellent | 387FPS min 245Excellent |
| Bottleneck (estimated) | CPU 67% | CPU 61% | CPU 41% |
The percentage estimates how much of the stronger component's capability goes unused because of the other one.
This one does matter: from the Intel Core i9-14900K downwards the processor becomes the brake on the RTX 3080 12GB. There is 5% between the slowest and fastest CPU in the table. One caveat: this is at 1080p, where the CPU weighs most. At 1440p and 4K the graphics card takes over and the processor stops mattering.
DLSS performance: FPS with AI upscaling
Upscaling renders Subnautica at a lower internal resolution and reconstructs the image, so you trade a little sharpness for extra frames. These are the estimated figures for the RTX 3080 12GB with DLSS enabled, starting from its native Ultra FPS.
| Resolution | Native | DLSS Quality | DLSS Performance |
|---|---|---|---|
| 1080p | 367 | 459 | 532 |
| 1440p | 306 | 413 | 505 |
| 4K | 176 | 255 | 326 |
About ray tracing: every figure on this page is with ray tracing off. The RTX 3080 12GB does have dedicated hardware for it, so you can turn it on in games that implement it. The FPS cost swings widely depending on how much ray tracing each title uses, and DLSS is exactly what people lean on to pay for it.
Estimated figures. The real gain varies by game and by the version of the technology.
Is the CPU or the graphics card holding you back?
These FPS assume a mid-range CPU that isn't a bottleneck — roughly a Intel Core i5-13400 — and 16 GB of RAM.
With that CPU, the RTX 3080 12GB has headroom to spare in Subnautica: the processor runs out before the graphics card does. A faster processor would gain you FPS; a stronger graphics card would barely help.
Is the RTX 3080 12GB Enough for Subnautica?
The RTX 3080 12GB delivers 367 FPS at 1080p Ultra in Subnautica. More than enough for 144Hz. You can comfortably play at 1440p.
At 1440p it gets 306 FPS and at 4K 176 FPS at Ultra quality.
This GPU is more than enough — you can play at 1440p or 4K comfortably
