Voodoo1 SST variables

The SST variables (Voodoo1 only)

Here are the main SST variables that you can add in your autoexec.bat by putting a line "SET variable" for each of them. You can also add them under a [3dfx] section of your win.ini (located in your Windows 95 directory) if you want to use them with Direct 3D accelerated games. Some will speed up your games or change the display, but some may be useless. Don't forget to write them in capital letters.
Example: SET SST_GAMMA = 1.65

Warning: do not overclock your card unless you're sure of what you're doing!

Variable Value Effect

SST_FASTMEM 1 Enables fast EDO RAM support.

SST_FASTPCIRD 1 Enables fast PCI bus support.

SST_GAMMA 1 to 1.95 Adjusts the global brightness.

SST_GRXCLK 50 to 57 This variable will overclock your voodoo card, so be careful. If you put a high MHz number, it may causes damages! The default value of all 3Dfx cards is 50 MHz. It's relatively safe to increase the number up to 57 (it's the Monster 3D "Maximum Performance" setting), but you should stop there. I tried to overclock my card to 57 MHz, but the gain in GLQuake was only of 3 fps, so I let it to 50 MHz. I also read some posts in 3DFX newsgroups that said that they destroyed their Flash 3D at 57 MHz! So again, be sure of what you're doing.

SST_BGAMMA 1 to 1.95 Adjusts the brightness of blue.

SST_GGAMMA 1 to 1.95 Adjusts the brightness of green.

SST_RGAMMA 1 to 1.95 Adjusts the brightness of red.

SST_SCREENREFRESH 60, 75, 85 or 120 Adjusts video refresh rate during 3dfx games. The smaller it is, the better is the quality. Default is 60 MHz.

SST_SWAP_EN_WAIT_ON_VSYNC 0 or 1 If it's set to 0, you'll increase the amount of fps but it can also cause tearing.

FX_GLIDE_SWAPINTERVAL 0 to 2 Same as above, but putting the value to 1 limits the fps to 60, and the value 2 limits the fps to 30, for a more regular animation.

SST_VIDEO_24BPP 1 Makes the card switch into 24 bit mode. You have to set it if you want to adjust the brightness with high monitor frequencies.

FX_GLIDE_NO_SPLASH 0 or 1 Disables (0) or enables (1-default) the display of the 3DFX logo when you start an accelerated game.
