Some of the Steam games in my library work fine, but a number of them suffer from stuttering, lag, and freezing that occurs only when the mouse is moved. Quake 3 suffers, but Return to Castle Wolfenstein doesn’t.
Star Wars: Empire At War works fine, but Age of Empires 2 HD edition appears to have this problem and the Cultures games are unplayable because of it.
I tried a number of searches online for fixes and none of the suggested fixes have helped. I’ve tried both a wireless and a wired mouse on different USB ports. Mouse acceleration is disabled, touchpad is disabled,… I even switched Windows Manager from XFCE to KDE because I read the Windows Manager could be the issue. I’m at a loss.
Any help would be much appreciated. Thank you.
