Cryostasis uses only one CPU core
 

This explains the performance issues most gamers are having. Cryostasis (as you can see here) uses only one CPU core. I'm sure the devs already know that (and if they don't... well... now they do know ;) ) so hopefully they will fix it :)

Thats true, ive also noticed it. :)

Use "CPU Control"
A simple tool allow you full control over your cpu cores usages.

0 - not used core for that application
1 - used core for that application

example:
1111 - this application use 4 cores
0011 - this application use 2 out of 4 cores
and so on...

enjoy :)

The game doesn't support multicores so you don't get any performance boost at all by enabling 2 or 4 CPUs (you are just wasting one CPU which isn't doing anything as it doesn't have any data to process). Already tried that after all and still the CPU usage is around 30-50% with my Core2Duo. It needs to be patched to take advantage of the multicores ;)

Yes... i did mention this too with my core2quad. :(
It seams its engine issue which can't take advantage of the multiple core systems.
WE NEED PATCH!

Υeah i have atlon x2 4400 and it doesnt use more than 50%!! Now i understanf why it is so slow!!:):):) Please someone fix it!

Cryostasis: The Sleep of Cores.

Anyway, really please fix this game! I have a q9450@3.6, 4gb of RAM and a overclocked gtx260. The game sometimes runs really slow, when there are a lot of dynamic shadows and intensive particle effects.

It's really annoying because the story is great!

Didn't you say that with the european-american version a patch would be published?

Everytime a only PC game goes out it's always heavy and unbearable for most configurations (like Crysis)...

Im afraid no patch will be able to make it "multi core optimized", Cryostasis is very similar to STALKER Clear Sky in this aspect, just a new engine could make this happen. :(

u guys really have performance problems?
i use e6600 overclocked to 3ghz with an 8800gts 640 mb and i can play it with everything max @ 1152 * 864 with ~26 fps.
i'm quite happy it runs that well.

Well at this low res 1152 x 864 it shouldnt be a problem, but 1680 x 1050+ yes, a multi core optimization wouldnt hurt.
