What do you consider 'acceptable' frame rates? I don't mind the 40's or 50's, cause I played UT for a year on a K6-2 350/TNT2u....so high frame rate are great, but I'm used to REALLY low, I could play at 1024x768 with 4x and still consider it playable, like no one else would. I don't do that, but I COULD is the thing.
