Frequently Asked Questions

What CPU do I need for Subnautica: Below Zero?
A Intel Core i5-11500-class processor meets the recommended bar. For high frame rates a AMD Ryzen 7 5700 gives more headroom. For 1440p+ gaming while streaming, a Intel Core i5-13600 or better is ideal. Verify any chip with our free Can I Run It checker.

Does the CPU matter for Subnautica: Below Zero, or just the GPU?
Gaming is GPU-bound, so the graphics card matters most for raw settings and resolution. But the CPU sets your frame-rate ceiling — it matters most at high refresh rates, at 1080p, and in CPU-heavy games (strategy, simulation, open-world). A weak CPU paired with a strong GPU causes a bottleneck.

Will my CPU bottleneck Subnautica: Below Zero?
It can, if your CPU is much weaker than your GPU. Check the exact balance of your build with our free bottleneck calculator before buying either component.
