-===== Description ===== 
-Returns true if the OpenGL renderer is being used by the client, false if software. 
- 
-When used serverside, this function always returns true and emits a [[ProgramError]]. 
- 
-It works by checking the following conditions: 
-  - The mod is being played in a GZDoom-based port (see [[IsGZDoom]]). 
-  - ''vid_renderer'' is true. 
-  - ''gl_nogl'' is false. 
- 
-Only if all three checks pass, the function returns true. 
- 
-<note important> 
-This function will return an incorrect value if ''vid_renderer'' or ''gl_nogl'' is changed mid-game because the renderer only actually switches after restart, but the values of the cvars change instantly.
