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.
http://www.overclockers.ru/softnews/27878.shtml

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.

I don't consider 26fps playable to be honest. It's really... shocking to see PhysX support and SLI support but not multi-cores CPU utilization.

@thales100: Actually a patch can save the day. Quake4 took advantage of multicores with a patch after all ;)

What are you talking about, I have a Q6600 and the game uses all 4 cores:

Granted, it's not the best multicore optimization I've seen (Unreal Tournament 3, Burnout Paradise, etc) but it DOES uses all 4 cores

You're using the DX10 Benchmark tool. Instead of that, run the actual game (both Russian and European versions) to see what we're talking about ;)

lol, I don't even have Vista, how could I use the DX10 benchmark tool? Those results are from running the game (European version)

Really ? Well lets give hope a chance. :grin:


ZIGS c é brasileiro ? I use my G15 + Everest Ultimate to check the CPU usage of my quad, only one core working during gameplay of russian version ( 0 - 1% for 3 cores, 98 - 100% one core) - pretty exactly the same i check when i play STALKER Clear Sky.
GTA 4, on the other hand, has a great multi core optimization.

This is ridiculous. The framerate is lower than Crysis at max settings, and it barely has to render a tenth of the content. The performance really has to be optimized, this is absolutely unacceptable.

thales100, sou Português :)

when I played the russian version, I'm pretty sure it only used one core too, so the EU version at least has that improvement (though I didn't notice any performance increase in the game itself... go figure).

Here are my results with Cryostasis. It seems that by showing one graph for the CPUs usage in Task Manager mislead me. HOWEVER both cores are running at BELOW 50% (in fact, a lot of times you can see that the game is using only the 30-35% of them). It is a seriously bugged CPU utilization after all

Beleza, cool :-P

your eyes and your brain work with 24 fps. u can't see more than 24 fps.
so it doesnt matter if u got 24 fps or 500. it will look the same for every human in the world.
so why it is not playable with 26 fps for u?

I had to register just so I could call you an idiot.

Humans can't see more than 24 fps eh? Do you know that to be absolute fact or are you just spouting something you've heard in the past from someone else who heard it from someone else. Yes, that's it exactly. The human eye is FAR more capable than YOU could possibly ever understand. This argument has gone around the Internet for far too long and is utter bullshit. If you could only process 24 fps then you, sir, would have been dead a long time ago due to an inability to think, see and react fast enough to prevent a multitude of hazards that humans encounter on a daily basis.

To fix your ignorance, click here to educate yourself.

Thats not true zwiebl, if you said over 60 or 500 i would agree, but 26 FPS is noticeable.
Btw Guru3D.com uses these limits for their GPU tests:

Are you kidding me, anything below 30 FPS is noticeable

I think 30 is the limit in most games, if they haven´t got motion blur. Cryostasis has motion blur so I think it´s really playable in 15 fps.

15 is too low imo. I think 25-30 in Crysis.

30~50 in crysis warhead and 20~30 in cryostasis.
And here the multiple cpu core support start to talk and scream ;)

Please don't feed the trolls :rolleyes:

This issue is really interesting. Cryostasis supports SM 4.0, hardware PhysX, SLI, X-Fi sound and... not CPU multi-threading ?! :shock:
On the other hand, there's not a lot of AI to take care of, so would multi-threading have made a big difference ? I wonder. Performance issues are more likely to be caused by improper PhysX support or resolution and graphical options set a bit too high... This game is as graphics-intensive as it gets, I'm not sure it relies a lot on CPU performance. To look their best and run smoothly, modern games demand an ok CPU and a killer GPU, not the contrary. I'll keep an eye on my task manager though ;)

Let's see then. Here are some results in a place that i am currently:

1024x768 + Max Settings: 34fps
1920x1440 + Max Settings (without Hardware Physics and Anti-Aliasing): 32fps
1920x1440 + Max Settings: (with Hardware Physics and Anti-Aliasing): 32fps

This clearly shows a CPU limitation, as the results are the same in high and low settings!

Good point, but I don't know what your config is ;)
I'm not sure I can really test this myself, as I'm using Vista64 and nvidia drivers are said to be efficiently multi-threaded in a 64-bit environment... Furthermore, 30% on each core compared to 60% on a single core IS effective multi-threading... I don't know what to think. Maybe I just need some sleep (of Reason).

Lower settings lowered the framerate lol

If the PhysX patch coming out soon doesn't fix the performance issues I'm done with the game. Who in their right mind makes an extremely intense game and doesn't support modern CPUs? I'm sorry to say, but that is, to use the word literally, RETARDED.

Oh and do the developers even read this? I mean c'mon! This is the official forums and I've never once seen a developer post.

I'm starting to like EA more, and that's sad. Freaking game says a lot of bad things for small-time developers such as 1C Company.

Sorry, but getting bad performance for no reason when I just spent a butt-load of money on building a good computer pisses me off.

My performance with Cryostasis isn't that awful, it's about 30-40 in crowded areas with lots of lights, etc and usually 45-60 in other areas.
This is on all maximum settings, 1440x900.
Of course, since the game only uses one core, this isn't as bad for me as it is for some users, as I have a Q6600 overclocked to 3.6g/hz so it's using a single 3.6g/hz core.
Some of you guys should really try overclocking your CPUs, it helps a lot for this game.

My PC specs:
Q6600 @ 3.6g/hz
GTX 295
4gb RAM
Vista32bit
Edit/Delete Message

Now I am a bit miffed here, some say it only uses one core and others have said it uses 2 and 4 cores.

But what really gets me is that I have only a

P4 3.4
2 gig mem
Radeon 3850 agp 512 mb, running shader 3.0 at 1360x768
all graphics ingame set to medium except for shadows set to low
on WinXP Pro SP3, all updates as of today.

And I get 50 to 65 fps in open areas and 40 to 55 fps in crowded ones and I only see slow down and no stutters. But it does stutter upon loading a new area for a second.

Now what gives here, is it because I don't have to use the PhysX stuff because of my agp card ???

Interesting Huh ?

Okay so the game uses all cores on your CPU, but the catch is the game doesn't use each core to it's max. Example: Dual-core CPUs will have each core running ~50%-55% while quad-core CPUs will run each core at ~25%-30%. It should be where quad-core and dual-core both run the game at 90%-100% each designated core.

No, it's not interesting. Your game settings are set extremely low. If I ran at those settings I'd probably get 60 frames per second with Vsync on (maximum). Although at that resolution the game would be blurry and stretched for me making the game unplayable.

EDIT: I don't mean to sound rude or anything, I am merely telling you why your computer performs so well at those settings.

" And I get 50 to 65 fps in open areas and 40 to 55 fps in crowded ones and I only see slow down and no stutters. I dont know whether u r lying or not....

but i have a tad better setup then urs yet with similar generation cpu nd i dont get

anything above 31 FPS (when snowing is off). flashlight on=14fps + when snowing

flashlight off= 17 FPS ( even on all low settings)

But there r few places where i see a massive jump on FPS. Tried HD audio to off but i have another options which is "opengl" and "no driver"

& where on earth u saw crowd on this game.????????????!!!!!!!!!!!!

P4 hyper threading 3.0 to 3.6ghz

HD 4850 ( yah i know im gona throw my cpu asap)

1.5gb ddr1 @480 2 4 4 8
