For players with AMD graphics cards

[Cumquat]

r_primitives [-1|0|1|2]

-1 = skips drawing

0 = uses glDrawelements if compiled vertex arrays are present, or strips of glArrayElement if not. (cvar r_ext_compiled_vertex_array "1")

1 = force strips

2 = force drawElements

 

There are even more and some look pretty weird, but they are locked ingame afaik.

they are not locked,you can do r_primitives 3 and your screen will be glitched with black spots etc
