Graphics problem

[Im_Sexy]

Excuse my English...
So...I played all Penumbra games and i really like them, but i kinda have a small issue with the requiem.I seem to have BIG amounts of lag even when i have all things off and smallest resolution.I can play Crysis on high damnit.So the issue is when i look around it like stands for 2secs and turns around and that isn't the only way it lags so please help me quick i really want to play the game without the lag .

wow seems like this IS Requiem's problem!
Hey mate, ive posted a similar thread to. I get major lag on requiem that i didn't get on overture or black plague. It makes the game really unplayable
What OS you have?
