Best Subnautica 2 settings for the RTX 4090 Laptop (2026)
On a RTX 4090 Laptop (paired with a balanced Intel Core i9-12900F-class CPU), Subnautica 2 runs at roughly 105 FPS at 1440p with our optimized settings — up from about 105FPS with everything maxed. Here's the configuration and what each setting costs.
The RTX 4090 Laptop is a high-end graphics card with 16GB of VRAM, and Subnautica 2 is a moderately demanding game. Paired with the Intel Core i9-12900F, it runs great at 1440p — about 105 FPS with 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 175 FPS at 1080p and 105 FPS at 1440p, dropping to roughly 80 FPS at 4K. Its 16GB of VRAM is plenty for Subnautica 2, so textures can stay maxed. The biggest free win is DLSS upscaling — set it to Quality for a large FPS boost at little visual cost.
| Resolution | All-High FPS | Optimized FPS |
|---|---|---|
| 1080p | 175 | 175 |
| 1440p | 105 | 105 |
