Hmmm, I went to modify my settings a bit to see just what the limits are on my current setup before I install the new processor tomorrow. When I was running Win98 my Nvidia control panel had settings for enabling/disabling Vsync, AntiAliasing, Gamma, etc. Now all those controls are gone! I checked in my control panel and found the Nvidia control panel icon, and it was turned off. So I turned it on, and while it did bring up more options than I had in the standard WinXP controls, I still have no way of affecting the biggies, esp. the Vsync and AA. Can anyone help me figure out what I've done here? Thanks.
