First Dragon Age ran smooth as butter with my 2x 260gtx's in SLI.
Now with DA2 I have 2x 460gtx SOC for SLI and its choppy as heck.
I installed the high rez textures and tried it all maxed out.
I get a fair amount of textures going black at certian points tho.

Trying to find the sweet spot for this now.
My CPU is still a 975e @ 3.9ghz.

But I have been running this installed OS for about a year now, with everything else. Maybe it's time to do a fresh install LOL
