How to Check if you are GPU or CPU Limited in CS2 (by @3kliksphilip)
- Launch any map offline.
- Set cl_showfps 2.
- Disable FSR and check the FPS.
- Set FSR to "Performance" and check the FPS again.
If the FPS increases, you are GPU-limited. You should keep the graphics settings to Low. Otherwise, you are CPU-limited. If you are CPU-limited, setting graphics to high won’t significantly affect your FPS.
