ezQuake Manual: OpenGL Rendering Variables

gl_affinemodels 

Description

Makes texture rendering quality better if set to 1. Note: 3dfx thing, not sure. //fuh check this.

Support: Windows: OpenGL Windows: Software Linux: GLX Linux: X11 Linux: SVGA Mac OS X FreeBSD

Default: 0

Variable is float.

gl_buildingsparks 

Description

Buildings that are destroyed in TF will continue to throw sparks until they disapear.

Support: Windows: OpenGL Windows: Software Linux: GLX Linux: X11 Linux: SVGA Mac OS X FreeBSD

Default: 0

Variable is float.

gl_clear 

Description

This variable will toggle the clearing of the screen between each frame. This can be helpful when specing a game and flying out of the map or during map development when the map maker must fly outside of the map to look has his map from the outside. Enabling this command will clear the areas which are not rendered outside of the map thus preventing the flickering effect when images repeat themselves repeatedly. However it causes problems when playing and going through the surfaces of a liquid (for example when diving into liquid), as you will see a red flash where the liquid texture would normally be repeated.

Support: Windows: OpenGL Windows: Software Linux: GLX Linux: X11 Linux: SVGA Mac OS X FreeBSD

Default: 0

Values

1On.
0Off.

gl_clearColor

Variable is float.

gl_cull 

Description

This variable toggles the use of internal OpenGL functions for removing covered objects. When this variable is set to "1" the game will depend on the OpenGL driver to use it's culling functions to remove certain objects from the calculations because they are covered up and would not be seen anyways. It is a good idea to leave this toggle enabled because it will increase rendering performance.
