February 16, 20206 yr Just happened upon this perusing a different topic on YouTube. On my system it worked amazingly well!!! All of the microstutters I had on taxi and in the view changes are gone - CPU 0 is no longer pegged, but load is balanced across all cores. Amazing!

February 16, 20206 yr It has the same effect on my system, Core 0 goes from 100% to 90%. Don't know about stutters because I don't haven them Edited February 16, 20206 yr by willy647 AMD 7 7700X, 32GB DDR5, RTX 5060ti 16GB, 2 x Samsung 1TB NVMe, 1 x 4TB sata SSD, Windows 11 Prof
February 16, 20206 yr Commercial Member That "tweak" has always caused my P3D to go haywire with stuttering. Strange isn't it? 🙂 Current system: ASUS PRIME Z690-P D4, Intel 12900k, 32GB RAM @ 3600mhz, Zotac RTX 3090 Trinity, M2 SSD, Oculus Quest 2.
February 16, 20206 yr This has been brought up on the LM forum several times over the years. LM advised against it as it would destroy the designed threading mechanism with core 0 being in charge of doing all management. But if it works for you without adverse affects, that's of course fine.

February 16, 20206 yr Before firing up P3D, I light up a candle. Performance increase of at least 0.002%. No kidding! Try it.

February 16, 20206 yr What you're really doing with this "tweak" is tricking the OS into swapping the main thread around to balance the load across the CPU cores. Note that this is actually *less* efficient than running the main thread on a single core, because now overhead is being incurred to swap the thread from core to core, which unnecessarily uses CPU cycles. 90% utilization on a single core turns into something like 23% across four cores...the same instruction sequence and thread blocks occur either way, so it isn't any faster or more efficient. Think of it like cooking muffins...you can put them into the oven for 20 minutes, or you can cook them for five in your oven, go to the neighbor's house and cook them for five more there, then move down the street again...etc. The muffins won't be done any faster, and it takes more work to keep moving them from oven to oven.

February 16, 20206 yr Well said! And what I would add is that with Nvidia driver 442.19, you can limit your fps in the Nvidia Control Panel (I have mine set to 29..) and this will cut back on your Core 0 usage.. So, now I have fps set to unlimited in P3D, vsynch off, fps capped at 29 in NCP, and I get smooth flight, and average Core 0 load of 60-70%.. This with a 1080p/60Hz monitor. Looking pretty good to me BTW, I still have my AM set to 253 (11 11 11 01) for my quad core CPU, but not sure it makes any difference to no AM.. Edited February 16, 20206 yr by Bert Pieke Bert
