Really nice post haven't really changed my con-fig because I'm not getting all the lag or stutter people are talking about. I would also recommend seta r_multithreaded_device "1" makes use of your multiple core cpu's. Though I'm not sure it had any effect on my game play or fps but it was set to zero as a default.
"r_displayRefresh "60 Hz" (was 75, i'm personally matching w/ my desktops highest choice w/ the hide box unchecked on an LCD (wouldn't do this with CRT but who has those anymore))"
I DO! it runs at 150hertz = 150fps bite me LCD users!
