ehh, 40.71 actually relieves the hitching, now i realize what that hitching is. in 40.41 and 40.52 ut2k3 playing a game on a server, i would notice the fps crawl to 0-20fps for about 5 seconds periodically about once a minute. at first i thought it was just server lag and such, as during 1 game i did not notice this hitching. now using the 40.71, i have yet to see ut2k3 hitch or stall, it runs perfectly smoothly online, and very playable at max settings. pretty good drivers..haven't yet to notice any problems, but i only play ut2k3, so yeah.
