If you are experiencing FPS drops or input lag in CS2 while using the Anti-Cheat, this may be caused by another application which interacts with the game.
If you have an AMD CPU, please read this support article, which contains a known fix for performance issues caused by certain AMD CPUs.
If you have Malwarebytes installed, the Anti-Ransomware feature can cause performance issues, we would recommend disabling it while playing.
The AC will automatically start the game with -allow_third_party_software, which means that any 3rd party overlays will work, whereas they would be normally blocked by default by the game if you don't use FACEIT AC. These overlays can result in performance issues, so we would recommend testing if these are causing the issue by adding -allow_third_party_software to your CS2 launch options from your Steam library, and/or testing without the Anti-Cheat. If you do not have issues while doing so, we recommend doing the following tests:
- Do not queue for any FACEIT match
- Start the AC and the game
- Play on a non-FACEIT server, e.g. Deathmatch
- Check if you have the issue here
If you are still having issues, please also try this:
- In Windows search box, type msconfig and open System Configuration
- Click on the Services tab, tick Hide all Microsoft services, select Disable all, then tick back Steam Client Service and FACEITService.
- Click on the Startup tab, click on Open Task Manager
- Click on the Startup tab of the Task Manager
- Select each Startup item and click Disable
- Reboot your PC
- Play a FACEIT match with only FACEIT AC, Steam and CS2 open, close everything else (you can check Task Manager to see and close any unwanted programs)
- Check if you still have the issue
If you are still having performance issues after following these steps, please open a support ticket and share the results of both tests so our team can help you!
