SMP scaling with STALKER

Though you all might like to know how much a dual core system helps with STALKER - Shadow Of Chernobyl

Test system:
Asus A8N-SLI Delux
AMD Opteron 165 @ 2.4GHz
2GB Patriot RAM DDR438 @ 2.5-3-3-5 T2
WD 160GB SATA 8MB
8800GTX (575/900)
Vista Home Premium 32bit

In game option maxed...2048x1536
float32 mod + darker nights mod
average of three 60sec runs using fraps
fps min/avg/max

1 core - 18/40/69
2 cores - 28/49/89

That's a pretty healthy increase if you ask me. Many people I talk to are still saying that we don't have enough apps taking advantage of multiple cores, but they're arriving now, and I was curious to what degree it was helping.

Nice, ive read also that oblivion is taking advantage of multiple core, not sure of the source tough.

Valve is adding multi-core support to the Source engine in the future. It's a big task, making an entire engine multithreaded. Check here for some deets. Sweet, eh?

I heard that on the elder scrolls forums, but it's really uses another core for the stuff that runs in the background for the game, IE: the movement and actions of NPC's that aren’t in the map your at, and other things that aren't directly related to the player.

thats strange, although the creators of the game claim it uses multicore cpus, on some articles on the net and when im running the game , the task manager shows only one core being used :? :?:

Well I've heard there is a patch somewhere to offload allot more onto the second core, but from what I understand what it offloads isn't much natively.

Durning gaming sessions, it looks like I have one thread using 100% (of 1 core) and another using about 30-40% (of the 2nd core), because my overall load in the task manager is steady at about 65-70% for the whole process.

I used a scripted flyby in the railroad yard as the major part of my benchmark so it would be easy to duplicate, see the video here:

odd...

What do you say about this?

can you do the same bench with a lower res like 1600x1200? maybe here a dual core isn't as needed as in resolutions above.

I own Oblivion and if it takes advantage of multiple cores, it does a very poor job of it. :roll:

Lower res would just make the game more CPU bound, so if anything you'll see even greater differences between single and dual core.

Anyway, this article compares dual core vs single core in many games, as you can see quite a few of the newer titles are multithreaded, including STALKER: http://www.digit-life.com/articles2/video/dualcore.html

Anyway, somebody mentioned Oblivion being multithreaded, that is indeed the case: http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=274...

An FX-60 (DC) @ 2.6GHz beats an FX-57 (SC) @ 2.8GHz by about 5 - 10%.

They did not compare all their dual core CPUs with any single core version, this has absolutely no relevence.
For me, STALKER is almost completely CPU bound. I notice about a 1-2% increase in performance at 1600x1200 and another 2-3% increase at 1024x768. I'll try to do them again with my current settings soon.

There was some improvement dropping the resolution down, but overall the difference isn't worth the loss in IQ IMHO. I'm very happy with the performance of STALKER with my CPU OCed, I was running for a while at only 2GHz and my minimum FPS were down in the teens, but with the OC to 2.4GHz, it runs much smoother, keeping the min FPS in the upper 20s.

what patches have you applied?

Sorry, I figured it was sort of a no brainer, but I guess it is important to know for sure...but it IS version 1.0001.
