On a Intel Arc B580 (paired with a balanced Intel Core i5-13500H (laptop)-class CPU), Subnautica 2 runs at roughly 109 FPS at 1080p with our optimized settings — up from about 109FPS with everything maxed. Here's the configuration and what each setting costs.
The Intel Arc B580 is a mainstream 1080p graphics card with 12GB of VRAM, and Subnautica 2 is a moderately demanding game. Paired with the Intel Core i5-13500H (laptop), it runs great at 1080p — about 109 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 109 FPS at 1080p and 65 FPS at 1440p, dropping to roughly 68 FPS at 4K. The biggest free win is XeSS upscaling — set it to Quality for a large FPS boost at little visual cost.
| Resolution | All-High FPS | Optimized FPS |
|---|---|---|
| 1080p | 109 | 109 |
| 1440p | 65 | 65 |
| 4K | 37 | 68 |
