You guys are just so terrible with getting things to work, cause all you cheapos are on your "mom's laptop" and still expect shaders to look good.
Get real. I have had an HD 5770 (for a while now) and it runs the shaders on high pretty ok with minimal lag. If you expect to play any of this on high with no lag: spend some freaking money.
My fullscreen works, my gui works, and I dont crash.
