oh and also is it better to have your... i guess graphics card settings... set to auto detect from software or game... or manually set them all to 16x filtering and 8x AA etc
and vsync off right?
I personally don't mess with the filtering and AA settings unless i do it in game. Most games will allow you to do this. You won't want it enabled in every game as sometime, especially with AA the performance hit is huge. As for AFiltering, the performance hit is usually really low.
Some games its just not supported and it'll cause it to crash.
