WINDOWS 11 - 2.9 on 14900k with all cores running AND IN BIN MT - NO stuttering

BACK UP YOUR REGISTRY PRIOR TO TESTING THIS IF YOU'RE AFRAID OF MESSING SOMETHING UP.

Hey all,

I think I pulled it off successfully. Here is what I did. 

Unparked all CPU cores:

1. Start>> Type "Registry editor" and click on the when search finds it
2. Go to: Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet
3. Click on "Edit" >>> Click "find" and search for:  dec35c318583
4. DOUBLE Click "VALUE MAX">>> Change whatever the number is to "0" (zero) and click OK and Exit the registry.

This unparks all your MAIN cores, not your threaded cores of which you have a total of 32. 

Now test DCS and see if you are still getting stuttering.

 

If you are still getting stuttering try setting the affinity in DCS to half your threaded cores. Here's how...

With DCS RUNNING in the background;

Bring up Task Manager

1. Hit "Details" in the side bar on the left  (I don't know where it is in Windows 10. If you do, let us know)
2. Right click on DCS and click set affinity
3. In the window that pops up, remove the checkmarks for the bottom half of your 32 threaded cores to disable them - hit OK.
4. Now you've basically told windows to use only the top half of the CPU's cores which may work for you. If not, try disabling the top 16 cores while re-enabling the bottom half of your cores. 

Conclusion: I played around with both these settings until the stuttering went away. Now I'm getting FPS upwards of 200, no stuttering and running all my threaded and non threaded cores after re-enabling all to test. Now I'm flying with all cores running in ST and MT with no issues. All my CPU cores are not parking. Yes - windows parks and unparks automatically depending on demand (like a flight sim) but it does this on the fly which means it does it while DCS is booting up. This may be a factor in DCS not running smoothly. the CPU and memory are working hard to bring up DCS while windows is telling the CPU to unpark all cores. I know I know.... In a perfect world this should not be happening. I don't know how it works. All  I know is that these two fixes FIXED my issue. 

 

Good luck and let us know how you did.
