lol fair enough, as you might be able to tell I am somewhat of a pc noob : P
Anyways, I find it weird that it is an optimization problem when I seem to get super silky smooth frame rates most of the time? Again, I am a noob and might be talking crap.
Either way I am sick of trying to figure this out, and if I can't get it working in a few hours I'm gonig to cave in and swap for the 360 version : (
EDIT - absolutely beautiful. Gamestation wont even let me swap my pc copy for an xbox version. This is just frigging great.
Returning PC Games never works

usually due to licensing or some crap. RealTek are pretty common on all motherboards for on-board sound. There's only about 3 makes including them that do it

(I have SoundMAX personally)
In terms of why it happens i really don't know - i've noticed that it happens for me usually when it's loading something important (I.E - it'll freeze and load a camp with npc's in the distance, while other times i can run along fine as it's just loading landscapes). If this is the case it's just an issue with how the objects are processed and *SHOULDN'T* be a big issue to fix
Saying that we've heard nothing from the mods / devs about it so i could be wrong
