Subnautica 2 benchmark on RX 7900 GRE: FPS by resolution and quality
Pick yours and we recalculate the whole table above with it.
Subnautica 2 FPS with a RX 7900 GRE and a Intel Core i5-13400
| Quality | 1080p (Full HD) | 1440p (2K) | 4K (Ultra HD) |
|---|---|---|---|
| Ultra | 98FPS min 68Good | 81FPS min 62Good | 46FPS min 40Acceptable |
| High | 128FPS min 89Excellent | 105FPS min 81Good | 60FPS min 53Good |
| Medium | 167FPS min 116Excellent | 137FPS min 106Excellent | 79FPS min 69Good |
| Low | 216FPS min 150Excellent | 178FPS min 137Excellent | 102FPS min 89Good |
| Bottleneck (estimated) | CPU 30% | CPU 17% | GPU 24% |
The percentage estimates how much of the stronger component's capability goes unused because of the other one.
This one does matter: from the AMD Ryzen 7 9800X3D downwards the processor becomes the brake on the RX 7900 GRE. There is 19% 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 7900 GRE with FSR enabled, starting from its native Ultra FPS.
| Resolution | Native | FSR Quality | FSR Performance | + Frame generation |
|---|---|---|---|---|
| 1080p | 98 | 123 | 142 | 209 |
| 1440p | 81 | 109 | 134 | 185 |
| 4K | 46 | 67 | 85 | 114 |
Frame generation inserts intermediate frames: it raises the smoothness you see on screen, but it does not reduce input latency, so use it selectively in competitive games.
About ray tracing: every figure on this page is with ray tracing off. The RX 7900 GRE 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 7900 GRE 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 7900 GRE Enough for Subnautica 2?
The RX 7900 GRE delivers 98 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 81 FPS and at 4K 46 FPS at Ultra quality.
