+''bool IsOpenGL()''
+===== 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 immediately.
