by screen tearing, you're referring to what exactly?? by my definition, screen tearing is where the game is being rendered at a higher frame rate than the monitor's refresh rate (ie, the game is rendering @ 70-100 FPS while the refresh rate is @ 60hz), and it causes the monitor to display pieces of 2 or more rendered frames in a single refresh.
its an easy fix: just enable VSync (or something similar), and it'll stop.
of course all that is dependent on whether or not the tearing is what you're referring to. if its different problem, well, i'm still here and ready to help.
