Poor performance in the demo.

[knifee]

When I first started Amnesia demo, I maxed everything out, only to be greeted by terrible lag. I finally managed to get some decent frames per seconds when turning line smoothing, paralax and SSAO off..I understand that they all are pretty performance heavy, but.. My computer can run mafia 2, crysis, metro 2033 on all high. Why cant I run this maxed out ?

Specs : Ati Radeon HD 5770, AMD athlon II X4 635, 2gb ddr3 ram.

I signed up here 'caus the Steam forums wont let me post

Anyway I had really low FPS with the demo, turning everything down to low got me about 2fps which was quite strange as like yourself i normally don't struggle to play games with the settings turned up.

Anyway I really wanted to play the demo so i played around a bit, and ended up as a last throw of the dice setting the cpu affinity to a single core. After this the game ran fine for me.

I dont know if this will help you, but i notice that you like me have a quad core CPU (although i have an intel), also the OP in the thread i wanted to reply to on the steam forums mentions that he has a quad core so perhaps there is an issue there.

Anyway I hope that helps.
