On a AMD RX 6700 XT (paired with a balanced AMD Ryzen 9 5950X-class CPU), Subnautica 2 runs at roughly 69 FPS at 1440p with our optimized settings — up from about 69FPS with everything maxed. Here's the configuration and what each setting costs.
The AMD RX 6700 XT is a strong 1440p graphics card with 12GB of VRAM, and Subnautica 2 is a moderately demanding game. Paired with the AMD Ryzen 9 5950X, it runs well at 1440p — about 69 FPSwith FrameCoach's optimized settings. That already clears a smooth frame rate on High, so our tuning keeps the visuals as high as possible instead of chasing extra frames.
Across resolutions you can expect around 116 FPS at 1080p and 69 FPS at 1440p, dropping to roughly 61 FPS at 4K. The biggest free win is FSR upscaling — set it to Quality for a large FPS boost at little visual cost.
| Resolution | All-High FPS | Optimized FPS |
|---|---|---|
| 1080p | 116 | 116 |
| 1440p | 69 | 69 |
