AllThis is an excellent in depth article on the nvidia control panel.It explains in detail every setting. Understanding these settings and the combinations available has allowed me to gain a few more frames. Of course there are sacrifices to some degree. It is worth the reading just for the understanding. I benefitted most by lowering the Image settings from High Quality to the Quality Setting. Many of the other settings are not available when the High Qaulity setting is used. This is where I had some options. This may be old news to some but thought I would post to help those who may be new to Nvidia graphics cards.I know there were some restrictions when posting URL's but could not remember. So if the link does not show correctly I am sure you can figure it out.RegardsBob www.tweakguides.com/NVFORCE_6.html

Just upgraded from an ATI 1900 to a 8800GTX. Saw an improvement of 5 fps. Tough getting this card to stay stable though. I had 4 gig of memory and it kept locking up. I removed 2 gig of memory and at least got it to stabilize. This was all based on an Asus A8n-sli MB

If you went from an ATI to an nvidea....did you clean up your driver before you installed nVidea driver?You need to uninstall your driver....and use some sort of driver cleaner and remove everythhing pertaining to your ATI driver including registry entries pertaining to that old driver.I think there is a CCleaner or something. Google for Driver cleaner and then reinstall your nvidea driver.Manny

Dont thinnk thats the problem - assuming its an XP OS, then 4 gig RAM was probably the problem - although XP is technically capable of using 4 gig in practice anything more than 3 usually causes problems, often traceable to the RAM slots on the MOBO itself - mixing and matching RAM is always undesirable, but matched sticks wont always work if four slots are occupied.Mind you, the 8800 is so new, and so are the drivers, so I woldn't make an issue of it until after the 100-series drivers are released specifically for the 8800.Allcott
