driver problems111

know this is because of my drivers, but these are the only one (xtreme-g) that resolve the AA bug 8800gt / gts has. never buying a nvidia card ever again, this is such bullshit. 90% of g92 users have AA bug and they just wont fix it. The performance is great, but the image quality is fucking shit. Worse than my old x1600xt. Moviemakers beware. :\

anyways i have this problem in ET with these drivers, textures / loadingscreen looks weird, like artifacted or sth, kinda tiled:

anyone know why this happens / have a solution?
