Poor performance on an awesome machine

[gargfump]

Hi, I have the very same issue, would be interested to know if u had any luck in fixing it.

I have more or less the same kinda setup as you, however a gtx260 on win7 32bit.
Also the same, i started the game for the first time with EVERYTHING on high, game ran perfect and smooth. Then i opened the journal and wanted to continue playing...terrible framerate lag, really bad suddenly.
So after having a brief look on the forum ofc, I turn SSAO quality down ( even though it worked fine justa second ago ) and yes the game runs a bit better...then area transition...BAM game slows down again...so i turn more stuff down, FSAA off etc...play ok for a while open the journal and game goes slow again.
Interesting fact it that once the game gets slow, it eve is in the main menu, where barely anything is loaded. And AGAIN i could run the game FINE with everything on high in the beginning.

Any suggestions would be welcome, while i continue to try to improve this.
( game isn't very scare if it's lagging hard )
