Skyrim Multy Thread Support.

[azmodan22]

Browsing in the net I found this page (http://itcprosolutions.com/skyrimguides/tweak_guide.htm) that has some ini tweaks, some of them suggesting that can make skyrim use more than one CPU tread.

My ini looks like this.

The graphics card I am using now is an 5970 Black edition and an enb for skyrim, thus I have the impresion that this .ini is not used somehow. Or at least as far as the card is concerned. 

 

However I did run Skyrim with the task manager open and I did see activity from all 4 of my CPU threads. So my question is simple.

 

Does Skyrim use 4 CPU threads (multy thread) by default, or would those tweaks described there will actually improve my games Performance?

You have to tweak it to make it use more then 2 cores, Skyrim will only use up to 2 cores by default. I only have 2 cores so never been able to try it out.

Playing around a few days with the tweaked .ini I have seen that those tweaks regarding multy threading support really did a difference. Skyrim's performance is almost doubled. The only difference is that in the page it suggests that if you have 4 or more, you should set it to 5 in the .ini. I found that if you have 4, seting the .ini number to 4 as well, skyrim performs better.

So even if one does see activity in all of the CPU cores, doing these tweaks in the .ini Will increase Skyrim's performance drastically.

I think it depends how many core you have some sites have placed tips to use one less so you have 4 set it to 3 etc..

 

But there are ini tweaks i am currently use also for animations.

take look at some options like:

bUseThreadedTempEffects=1
bUseThreadedParticleSystem=1
bMultiThreadMovement=1
bUseThreadedMorpher=1

 

[backgroundLoad]
bBackgroundLoadLipFiles=1
bLoadBackgroundFaceGen=1
bUseMultiThreadedFaceGen=1
bBackgroundCellLoads=1
bLoadHelmetsInBackground=1
bUseMultiThreadedTrees=1
bUseBackgroundFileLoader=1

 

[Animation]
bMultiThreadBoneUpdate=1

 

[HAVOK]
iNumThreads=3

 

[Decals]
bDecalMultithreaded=1

 

 

 

This part:

[HAVOK]
iNumThreads=3

 

Tells the game how many threaded to use in game. in one sample i used 4 threaded and the other 3 threaded.
