cg_simpleItems "x". A value of 1 will disable the display of 3d models for items, instead using 2d icons in their place, this may increase frame rate on older videocards. 0 enables the display of 3d models for items, which will make image quality a little better.

com_introplayed "x". A value of 1 for x sets that the Intro (with Sarge) is played every time you load up Quake3. Give it a value of 0 to disable it being played.

The next 5 settings may help those of you that get motion sick (like myself). It will also make aiming/shooting a target while you are moving a little bit easier as an added bonus.

cg_bobup "0.00x". This setting determines how much you bob up while moving. Leave it at the default value or 0 to remove the movement.

cg_bobpitch "0.00x". This setting determines your pitch up while moving. Leave it at the default value or 0 to remove the movement.

cg_bobroll "0.00x". This setting determines how much you roll back & forth while moving. Leave it at the default value or 0 to remove the movement.

cg_runpitch "0.00x". This setting determines your pitch while running. Leave it at the default value or 0 to remove the movement.

cg_runroll "0.00x". This setting determines how much you roll back & forth while running. Leave it at the default value or 0 to remove the movement.

r_allowSoftwareGL "x". Set x to 1 to allow software rendering of the game. Although this really is an extremely bad idea unless you absolutely cannot run the game with your current video card. Get a new video card if this is the case, or try updating your drivers. Leave it set to 0 at all times.

r_clear "x". A value of 0 for x fills cracks between textures, 1 makes these visible. 0 is slower than 1 although more pleasing visually.

r_colorbits "x". Use this to set the colour depth. Leave it at 16 unless you have a card that supports 32-bit colour output. Performance is slower in 32-bit than 16-bit however. So when you play online be sure to drop this back to 16.

r_depthbits "x". This is similar to the setting above. This sets the colour depth bits per pixel. Valid values are 16 or 32, setting it to 0 will use the same colour depth as the Windows desktop. Selecting 32 (If your video card supports it) will give best image quality, but slowest peformance.

r_detailtextures "x". Set x to 1 to will improve texture quality when up close. Setting it to 0 will improve performance.

r_displayRefresh "x". Use x to set your refresh rate in the game. It is recommended that you set this to the highest refresh rate that your monitor can handle at a given resolution. With vsync enabled this value also limits the highest frame rate you can achieve. You shouldn’t set it any higher than the highest refresh rate your monitor can sustain at a given resolution.

r_drawSun "x". A setting of 1 enables the sun to be drawn. It won’t improve performance much if set to 0 although it will add a little to lighting calculations in areas where the sun shines. I suggest leaving it set to 0 as most maps will be played “in-doors” or have few areas with sunlight (Quake 3 has no outdoor levels).

r_dynamiclight "x". A setting of 1 will enable the dynamic lighting of maps, e.g. the light surrounding an explosion. Improve performance by setting this to 0, although visual quality will be reduced.

r_ext_compressed_textures "x". Set this to 0 to disable texture compression support (slower, but better visuals). This is only for S3TC texture compression so if you have an S3 card, are using the 5.xx nVidia drivers or have a Voodoo 3, 4 or 5 installed then you should set this to 1. Texture compression can vastly improve frame rates, although may cause some visual degradation in certain areas of the game.

r_ext_multitexture "x". Set it to 1 to enable multi-texturing, this can improve performance. 0 will disable it.

r_fastsky "x". A setting of 1 will remove the sky texture & portals won’t be seen through. I’d recommend leaving this set to 0 unless you’re on a really slow system.

r_gamma "x". Default is 1. Increase this to make the game brighter. The brighter the visuals the more washed out the textures will look (not quite the same as the brightness setting though). This adjusts the RGB colour intensity. Higher values will reduce texture detail by brightening textures up. Performance isn't affected.

r_ignorehwgamma "x". Set x to 1 to enable the game itself to set the gamma level to be used. Set it to 0 to disable any in-game gamma settings & use one set by the video card driver instead. Setting it to 0 may make any brightness slider in the game menu ineffective.
