Trees Popping

This is what is safe to do in Threads from: http://www.nexusmods.com/skyrim/mods/50244

 

Threading Changes

Following is the DEFAULT settings Skyrim uses:

iNumHWThreads=4

iHWThread6=5

iHWThread5=5

iHWThread4=5

iHWThread3=4

iHWThread2=4

iHWThread1=4

iAIThread2HWThread=5

iAIThread1HWThread=3

iRenderingThread2HWThread=1

iRenderingThread1HWThread=0

Here's the simple truth. If you have 4 cores, or 2 cores, don't change this. Just don't. Remove it from your INI file if you have.

Skyrim by default uses 4 cores of your CPU (iNumHWThreads=4). These cores/threads are each allocated to different tasks. The variables are perfectly set to leave room for different tasks by default. For example, notice the gap between Rendering and AI, there is one thread free. This is used for the audio thread. There is a gap between the AI threads too, used for 3 of the HWThread's. 5 is shared with AI Thread 2. This is a wildcard of sorts. This works for 4 cores, and should be left alone.

If you have 8 cores however (Hyperthreaded too if you're brave), you have the option of moving the work of iHWThread4, 5 and 6 to a separate core from iAIThread2HWThread, and telling Skyrim that you have 8 cores, not 4.

Add these if you have 8 cores.

iHWThread6=6

iHWThread5=6

iHWThread4=6

iNumHWThreads=8

Havok (Skyrim.ini)

Believe it or not, changing this value is not a good idea. Havok is set to 1 thread by default because there's only one thread to spare. Increasing this to 4 will cause Havok to share thread's with tasks like AI and Rendering, which will ultimately hurt your CPU more. Even with an 8 core CPU, just leave it to 1 thread. We don't know enough about Skyrim's thread allocation to be sure that it won't share the second thread with tasks like AI.

Remove the following from your file if you've added it.

[HAVOK]

iNumThreads=

OK, I have 6x2 cores, so 12.

Any settings to be good with 12 cores?

[Project579]

Use the 8 core setting Skyrim was never tested with more then 8 cores and it might cause a performance loss because game load is not balanced between cores very well.

OK Thanks
