I get the message “no RGB fullscreen modes available” when I run GLQuake. What does this mean?
This means that your desktop’s display color depth in Windows 95 is set for less than 65,000 colors (also known as 16-bit color or High Color). You must set your color depth to at least 65,000 colors. To do this, double click on the “Display” icon in the Win95 control panel, select the “Settings” tab, and select “High Color (16-bit)” under the Color Palette setting.
