You DID know that turning V-Sync off makes it pretty ok, right?
(The game was still a borefest, though...)
Turning off V-Sync did indeed solve the problem with the mouse, but at least on my system it turned on the horrible, horrible screen tearing.
Funny that, I always turn it off and never get any tearing. What causes it anyway?
i never experienced it aswell, but if i am correct it can happen if you have very powerful machine and you get ****loads of FPS (200+) on your 60Mhz LCD... Dont hit me if i am wrong
It's basically the screen is half way through being drawn when its displayed, the screen shows 60 frames per second, v-sync locks this, essencially slowing the rendering.
Technically anything over 60fps on a 60hz monitor will lead to tearing.
