Warhammer Online

Well, my latest obsession has been Warhammer Online. It's a pretty good game, however, it seems to lack something that I miss from World of Warcraft. It just seems like the graphics aren't as fluid and controlled like WoW. It could be my system, but I doubt it. I have an AMD64 dual 2.4GHz processor, with two 8600 GT's in SLI. With this horse power, i should be able to see amazing graphics, but I almost had to put it down to 1280 x 1024 just to get the frame rates bearable. Could be that running the game on a 64 bit machine isn't quite working, but everything else seems to work fine. If anyone knows the answer to this, please let me know!
