major lag on Requiem

[Im_Sexy]

Hello finally ive got Requiem but the lag on it is unbelievable...

If i remember, in Overture or Black Plague i didn't have problems like this! I mean i made it to level 3 on Requiem and every room is lagging. Ive set the configuration like the others, in the lowest resolution, putting only static shadow, medium effects/texture...but still the game frame isn't good..

Can someone tell me other options to set to lower or something like it?
Or this is a Requiem problem?

Thanks
