Thats EVERY Cvar. Not the ones for the display. Any thats cg_draw is mostly HUD ones.
cg_draw2d
cg_drawfps
cg_drawgun
cg_drawreinforcementtime
con_drawnotify
cg_drawteamoverlay
cg_drawfireteamoverlay? cg_fireteamoverlay?
If its for making a movie its simply just a case of removing everything but drawgun and the frag message. Tbh, it should now be easily possible for someone to make a demo mod that hides everything but that? Easy enough to create custom hud layout displaying what you want and how you want… would also look nice in a video when peeps see it and think, htf does it look so good? :]
