I may go into how awesome Quake 1 is someday, I want to address a common problem with newer video cards and graphics chipsets: GLQuake won't work!
- Delete (or rename or move) opengl32.dll from the Quake directory.
- r_wateralpha .8 will make the water slightly transparent
- r_mirroralpha .8 will make slipgates kinda transparent
- +mlook will make the mouse work better
Speaking of brightness, what about Quake II? Sure, it wasn't that spectacular of a sequel. It was a departure alright. But, with modern systems the game may be too dark. Here's what you do:
- Access the configuration file at \%Quake2%\baseq2\config.cfg
- Look for gl_modulate and change the number to 2.5
- Look for gl_shadows and change the number to 0
- Save and play!
