Ensure your game is in Borderless Fullscreen.
Fullscreen prevents overlays from displaying properly.
Set your monitor to your stretched resolution before launching CS2.
The overlay automatically scales with your aspect ratio.
Make sure no external anti-cheat systems (e.g., Vanguard or Faceit AC) are running.
These can block memory access.
Disable the following Windows options:
- Optimizations for windowed games
- Hardware-accelerated GPU scheduling
- Variable refresh rate
- Game Mode
In CS2 settings, disable:
- FSR
- Anti-Aliasing
If you’re getting this error:
- Remove any Anti-Virus or Anti-Cheat software.
- Apply the registry fix below, then restart your PC.
