This is a fix for the new beta drivers released by 3dfx. The new drivers work great for the fixes to the Visual Reality software, but the 3D performance is awful. This will fix that problem. You must first install the beta drivers and Visual Reality software betas posted on their site. Then, extract this file and click on setup. It will appear that the setup does not get completed, because it only replaces 2 DLLs (2 of the older ones from earlier drivers). After that, restart your computer and enjoy your 3D games.
