RivaTuner is a hardware monitoring program, when you’re running it at the same time with Overwolf, it might cause performance issues in your games, such as low FPS, mouse movement lag, freezes and more.
How to overcome this issue?
One way would be to close RivaTuner while you’re using Overwolf in games, but if you don’t wish to completely close it, you can change the program’s settings as follows:
- Set “Application detection level” to “Low”
- Set “Stealth mode” to “OFF”
- Set “Custom Direct3D support” to “OFF”
- Set “On-Screen Display coordinate space” to “Framebuffer”
