windows upgrade kills cs:source fps?

[ngk]

i had been running windows xp pro with no service packs or anything for a very long time. i have a custom config from the cal open forum (casey's config) i used to get about 100 fps in the video stress test and very good fps in game constantly.

two days ago i upgraded my xp to a different key and sp2 with all available updates....at first my stress test was about 90 fps with 81.98 forceware drivers, i then downgraded back to my old 78.05 drivers and my stress went to about 93 but i still get down into the red and yellow with cl_showfps 1 or whatever....

just wondering if there is anything else i need to check, i'm running the exact same hardware and config files but maybe i missed something...

thanks

It's definately the last update. Check the forums at www.steampowered.com

Edit: Just so you don't waste your time, there's no known fix for it right now.
