Default value: "1"
Saved to config.cfg: no

Engine: GLQuake

gl_ztrick enables/disables the use of a trick that allows the renderer to avoid clearing the depth buffer every frame. This results in a slight speed increase, with a trade off for less depth precision.

(The performance gained from turning this on is barely noticeable on newer accelerator cards, so it would be better to turn it off if you have a TNT2 or better)
