Well, first of all, never use any preset MSFS gives you. Key is to understand what each setting does, which ones affect CPU and which ones affect GPU, then load your system accordingly. Use this guide right here to fine tune your settings while keeping an eye on CPU (MainThread) and GPU load using the dev mode FPS counter.

This is great! What is Ambient Occlusion? I see 0 difference in any of the pictures.  🤔

Ambient Occlusion creates somewhat realistic contact shadows. You will see the difference when close to a Terminal, or on the parts of the fuselage that are in the shadow, it's subtle but makes the image much more realistic. I recommend "High" if your GPU can do it.

Yes i tried locking from 45 all the way down to 32. Tried with G-Sync on/off. Its like something in the CPU utilization gets screwed up after some flying around. Even in remote areas.

One thing to try, recommended elsewhere, is install "Process Lasso" (it is free with a nag) and disable Windows dynamic thread priority boosts. I gather it stops windows randomly swapping your processor priorities away from MFS at inopportune times. 

 

Might help, might not .. but its free so no harm in trying.

OKKK i think i am onto something(AGAIN). Software called "Park control"  The most interesting value there is "Freq Scaling DC". 

I set it to Enabled and and put 100% then press apply. 

If someone having similar issue with stutters as me, please try and let me know. I know this could work now and after 1 hour it wont.

Down a rabbit hole... 😉

It looks real good now. Here is what i think is happening and @w6kd feel free to correct me if i am wrong.  Since this sim CPU use is low, the processor think its not in use much and reduce the CPU freq. Thats why sudden moves or just flying to new area causing stutters because its all of a sudden wake up. Am i making sense ?

This must be it ! I just did a 30 min flight with almost no stutter at all. I am so happy i am afraid to close the sim just so when i open it next time it will be back 🙂

So what settings did you set exactly?

Profile on top "ultimate Performance" , Below it the 3 options from the left to right set to Disabled and 100%, the last one "Freq scaling DC" set to Enabled and 100%. Click Apply just under it. Dont click OK on the bottom just navigate back to the sim. Check and please let me know i am very curious to know your result.

Okay I used the bitsum power profile in process lasso, which is supposed to do the same thing, I definitely notice it being way smoother. Need more testing.

For me it made a difference like night and day. only question now is if i should try to put back on the HT. Now that i found the real cause. I could just try but i am actually afraid to touch anything 🙂

I have a few more test flights. This really does make a big difference. On smaller GA aircraft that are not too heavy on the frames to start it is butter smooth. The 787 is not as smooth, but I can say it is much improved. Thanks roi1862!

Glad to hear it ! Yes its not perfect still but its playable now. Hopefully future optimizations will make this smoother.

Before it was like I could only focus on the stutters because they broke the feeling of immersion. Now they only really seem to happen during communications, which is not bad at all.

Interesting find - thanks. Who knew lower CPU usage would cause issues...I wonder if disabling C1E and EIST in BIOS would accomplish the same?
