well a 2003 engine updated with shaders, hdr, auto exposure, antialiasing, anisotropic, that runs smooth on a decent rig with 150 players...
i'd say one of the best indie graphic engines so far (because armagan and his wife programmed the 3d engine from scratch... just them.)
Electronic Arts instead fields zillions of software engineers to bring photorealism to the games, but the games they make really sucks.
EDIT:
and btw the graphics don't suck at 1680 with 4x AA and 16x AF with all maxed. and the blood mod is really a nice boost in eyecandy.
Fuck it. I play it on DX9 with lowest settings (pluss particle effects) and it still looks good to me. Better than what a lot of Ubisoft, and even some of what EA, has put out. Only new game I've seen lately that is good and runs like a charm on anything is Deus Ex: HR. Awesome tech behind the game there too. But Armagan wins though, since he's also an Indie developer. Mad skills on that guy.
