Subnautica benchmark on RX 6750 XT: FPS by resolution and quality
Pick yours and we recalculate the whole table above with it.
Subnautica FPS with a RX 6750 XT and a Intel Core i5-13400
| Quality | 1080p (Full HD) | 1440p (2K) | 4K (Ultra HD) |
|---|---|---|---|
| Ultra | 227FPS min 122Excellent | 168FPS min 101Excellent | 74FPS min 64Good |
| High | 295FPS min 159Excellent | 218FPS min 131Excellent | 96FPS min 84Good |
| Medium | 386FPS min 208Excellent | 286FPS min 173Excellent | 125FPS min 109Excellent |
| Low | 500FPS min 270Excellent | 370FPS min 223Excellent | 162FPS min 141Excellent |
| Bottleneck (estimated) | CPU 57% | CPU 46% | balanced |
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 RX 6750 XT. There is 8% 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.
FSR 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 RX 6750 XT with FSR enabled, starting from its native Ultra FPS.
| Resolution | Native | FSR Quality | FSR Performance |
|---|---|---|---|
| 1080p | 227 | 284 | 329 |
| 1440p | 168 | 227 | 277 |
| 4K | 74 | 107 | 137 |
About ray tracing: every figure on this page is with ray tracing off. The RX 6750 XT 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 FSR 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 RX 6750 XT 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 RX 6750 XT Enough for Subnautica?
The RX 6750 XT delivers 227 FPS at 1080p Ultra in Subnautica. More than enough for 144Hz. You can comfortably play at 1440p.
At 1440p it gets 168 FPS and at 4K 74 FPS at Ultra quality.
This GPU is more than enough — you can play at 1440p or 4K comfortably
