Hiya folks. I'm a loss here. I have a ATI 5750 card, 1 gig of ram, from XFX. It runs the game pretty decently on standard texture quality, high on the filtering, and shadows at lowest, at 1680x1050 fullscreen. It still lags a bit in LL, but Uldah and Grid are fine, no noticeable lag. Yesterday I switched out this card with a 260 GTX Core 216, with 896 megs of ram, from EVGA, and running the same settings, I'm getting tons of hitching, lag almost constantly in town, out of town, pretty much anywhere I go. I went to LL to do some quests and it was crawling. Now I'm lost as to what is wrong. From everything I've read across tech forums, the 260 is supposed to outperform the 5750 easily, but yet it isn't. I have the drivers updated, and the old ATI drivers removed. Any help solving this weird puzzle would be greatly appreciated.
