Problem with STALKER, or my 8800?

[Greenboi]

Well ive just installed my new hdd, and got stalker on it, patched etc...started playing, its great!

Well i was playing about 10 mins when i noticed the fps drop from 60 to about 25 or below! this was a sudden loss, just happened, even looking in the same place i was before!

So i tried minimizing the game and opening it back up...and my fps shot right back up to 60+..what the hell?!

I think this has happened in other games too...but alt-tabbing out seems to fix it, but it is very annoying to have to do that every time i play the game every 10 mins or so when this happens!

Anyone else have this problem of random fps loss? Is it 8800 shoddy drivers? (on 158.22's by the way) Is there any fix for it?!

Thanks in advance

Temps arent too hot... but all i have to do is alt-tab out of the game then go back in and its all back to normal.. its doing it on every game (TDU, Oblivion, STALKER, Dark Messiah..)

Oblivion seems to be fine, just played it for 10 mins+ through forests and in the oblivion gates.. 40fps in forest and 40-60 in plane of oblivion..sound right? seems okay

Also ran 3d06, got 10.7k...so it must be STALKER
