Subnautica 2 benchmark on RX 6800: FPS by resolution and quality
Pick yours and we recalculate the whole table above with it.
Subnautica 2 FPS with a RX 6800 and a Intel Core i5-13400
| Quality | 1080p (Full HD) | 1440p (2K) | 4K (Ultra HD) |
|---|---|---|---|
| Ultra | 73FPS min 57Good | 59FPS min 51Acceptable | 36FPS min 32Acceptable |
| High | 95FPS min 74Good | 76FPS min 66Good | 47FPS min 41Acceptable |
| Medium | 124FPS min 97Excellent | 100FPS min 87Good | 62FPS min 55Good |
| Low | 161FPS min 126Excellent | 129FPS min 112Excellent | 80FPS min 71Good |
| Bottleneck (estimated) | CPU 15% | balanced | GPU 42% |
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 i5-13400 downwards the processor becomes the brake on the RX 6800. There is 25% 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 2 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 6800 with FSR enabled, starting from its native Ultra FPS.
| Resolution | Native | FSR Quality | FSR Performance |
|---|---|---|---|
| 1080p | 73 | 91 | 106 |
| 1440p | 59 | 80 | 97 |
| 4K | 36 | 52 | 67 |
About ray tracing: every figure on this page is with ray tracing off. The RX 6800 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 6800 has headroom to spare in Subnautica 2: the processor runs out before the graphics card does. A faster processor would gain you FPS; a stronger graphics card would barely help. At 4K it flips: there the graphics card becomes the limit.
Is the RX 6800 Enough for Subnautica 2?
The RX 6800 delivers 73 FPS at 1080p Ultra in Subnautica 2. Enough for a smooth 60 FPS experience. For 144Hz, lower the quality to High.
At 1440p it gets 59 FPS and at 4K 36 FPS at Ultra quality.
