ive already decided on a few tweaks that i use in this file, however i want to hear what other people are doin to make their game run better.  and can anyone tell me what the 'NVPerfHudEnable' setting does, if it does anything at all cause i have a 6600gt and i would assume if it recognized that it would turn it on but its off by default, im asking because im assuming the NV thing stands for nvidia.  and what about 'isloadingtexturesinbackground' is this one good or not i have 1.5 gigs of ram so im thinking better for it to be off for better average HD performance in the game.
