Great job Nvidia...with these new drivers multi-core support in Left 4 Dead is bricked. If you update to the 180.48 drivers and experience random stuttering in Left 4 Dead it's probably the multi-core issue at work. Disable multi-core support in the game and things will smooth out.RayvinAzn

"Expand" button in user profile doesn't work on FireFox 2 or 3 or Internet Exploder 7.0.5730.13.

At wide launch when it did work in FF 2 and Exploder, it took way TOO long to load, even on faster bandwidth. REALLY miss the dropdown for "My games" list which offered better functionality for me as a user as I referenced that feature the most of any on gs.

Please bring the dropdown back.

The links issue seems to be fixed now. When I get email updates the links now work. Also, where i had links taking me to the wrong content was on the UT3 maps download links, but those are working correctly too. I remember having link issues on other areas of the site/content, but I can't recall where specifically.

All seems to be working fine now, thanks for your help.
