Small tip to you folks using old crappy display cards:
Set the anti-aliasing tab in d3d properties MANUALLY to off position. I've noticed a notable performance loss if it's set to 'let applications handle' even if applications are _not_ using FSAA. Things just go smoother with it set manually off.
Another performance trick is to set anisotropic filtering off, even to the limit of setting it totally off ( not even double buffering. )
That makes textures look real blocky, but fps will go up quite much if you need speed instead of looks.
Oh, and you who suffer from mushed text, try setting down your buffering level also. Set it to 0 and see if your text still looks bad.
