@Georgiegril: - Hmm, I don't think any of the screenshots on that page match. I just played Saints Row Third- a little slow in full screen, but ran fine when windowed at a lower resolution with low settings. My sister played Resident Evil V- fullscreen, without issue. Previously (when on Vista with 1.5) Skyrim was fine on fullscreen, and low settings. The problem started after I switched to Win7-32, using 1.5. Thought 1.6 would solve the problem, but it didn't... - I did upgrade my drivers, but it didn't help. - Cleaning is something I've never done... I think I'll give it a try. -Texture mods? I'm using CBBEv3 and Ashen. I didn't have any trouble with it before, but I'll try disabling them first and see what happens. -Yup, all programs closed, though I leave one light program open just to make it easier to alt-tab. -DirectX should be up to date, seeing as I just installed Sants Row Third recently- I'll have to check and see. Thanks for all the suggestions, by the way!
