One day I noticed that all the programs listed in the Nvidia program selection area were missing. I even reinstalled the driver and they still aren't showing up. Its annoying because now when I try to add cs:s and hl2 to the list, it is recognized as the exact same executable, whereas before, the list would let me change the settings for both. Any suggestions as how to fix this?
hmm,roll back to an older driver and see if it works
I went to nvidia.com and went to the page to downlaod the most current driver 186.18. On the left side theres is win xp64 driver archive. The last driver says April 5th, 2007. Was that the last driver for x64? It's hard to believe that.
