Extreme lag on opening screen/menu/game

[daedalus871]

Have you tried lowering the number of SSAO samples? It may sound silly if you have a good amount of technical skill and already tried it, but if you just set everything to maximum without looking, that would mean you have it set to 128. This means it would need to render the SSAO 128 times per frame, which caused a lot of lag for me.

Thanks for your help, but i tried the saso combinations. I even tried changing everything in-game through the options menu. It took 20-min(I timed it) due to lag and it was unsuccessful. I was thinking that it may be a directx issue. I just started Red Faction Guerilla and it had some amazing lag, only in campaign, but i fixed it with "-no3d10" which made it use dx9. However, Amnesia doesnt have an option like that(that I know of)
