I was just in the middle of playing the new Borderlands game, when suddenly all the models started getting stretched out and I have constantly changing purple dots everywhere. I closed to my desktop and its still there!
I uninstalled the drivers, and then the dots went away, re-installed and boom they're back.
This is what it looks like in TF2
I'm quite the noob, this is my first build and it was working great until now.
