lol... I used r_showtris to find it... and such shaders/models in theory can reduce fps a bit (not in this case it seems).
I never played Doom2 and I blame its game style full of heads, blood and dead bodies. I would ask who John Romero is, but I already found him at Wikipedia through Google (now I finally know who that is, lol).
Fixed the pic... my other image host site is under maintenance haha...
Does Cerberus have some secret too?
