Another important feature (and indeed simple to implement) to consider is V-sync. By turning the function off you'll see an immense improvement in your in-game frame rates. For Glide based games you'll need to simply add in a single line into your autoexec.bat file found in the root directory.

SET FX_GLIDE_SWAPINTERVAL=0

D3D has certainly matured into an incredible API (some game developers will of course argue against that) but… You can of course thank Microsoft for having to go in and edit your registry to simply disable the v-sync for D3D games. As long as 3dfx wishes to remaim WHQL compliant they can't support the V-sync DISABLE feature within their drivers in the control panel.

Simply locate the correct directory within your Windows registry, which is:

[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Display\000X\D3D]

Then simply add this string value:

"SSTH3_SWAPINTERVAL"="0"

With those registry settings your D3D games will no longer be synced to your monitor's refresh rate and hence the frame rates will soar.
