VIDEO_FILTER_DISABLE Disable 24-16 bit dithering (This attempts to smooth dithering artifacts) (causes complete loss of signal to monitor)
VIDEO_FILTER_TRESHOLD 16bit pixel value theshhold, in which smoothing will be applied to inside adjacent pixels. Controls how much filtering is applied to dithered pixels
VIDEO_NOCLEAR Don't clear backbuffer during a page flip. Disables automatic hardware clearing of frame buffer(s)
VIN_CLKDEL Single Voodoo system video in clock delay Number of clocks to delay video input from a master
VOUT_CLKDEL Single Voodoo system video out clock delay Number of clocks to delay video output to a slave
VSYNC 1 0 or 1 Disable vsync, may increase performance (0) Forces glide to use a VS lenth of n video clocks
I have several questions concerning these:
1.) To activate these where to I type them in and how?
2.) If I change a given setting will I need to restart Windows or will the driver reintialize itself every time a game or 3d demo is started?
3.) Which of the above are most important?
4.) Does anyone have a more detailed list with explanation/guidelines how to set the options up?
5.) Will all the settings I implement be used in Direct3D/OpenGL and Glide games etc?
If anyone has some or all the answers to the above questiosn then please be kind enough to leave you comment/help on this thread.
P.S As extra information the system has 2 Voodoo2's in SLI and is running both Windows 2000 and Windows Me.
Profound thanks,
Adam
