Setting it to low did, unfortunately, nothing to solve the issue.
In regards to the older graphicsdriver. How would i go about doing that?

Edit: I tried the theory with the lower settings again, but this time i had medium textures. Seems to be working alot better for some reason.

I'm having the exact same problem. I too use the GeForce 9600GT and tried turning vsync on and disabling antialiasing.
Such a shame that it does this.
