Here is the follow up, and I sincerely hope this helps others solve the persistent stuttering issues that have plagued this sim throughout most of its existence.
The stuttering was definitely caused by the CPU. It didn’t make sense to me that a 10th Gen i7 couldn’t keep up with MSFS, but at this point I believe it to be a combination of Asobo’s code slamming the processor and HP’s cooling system design (which isn’t very good) in the Omen laptop falling behind. The stuttering was in fact caused by the CPU bouncing between turbo mode and throttling due to heat. While the CPU is capable of 4.5 GHz +, once the heat builds up it attempts to protect itself.
As was previously suggested I used throttlestop to look at what was going on and make some changes. I changed the max speed that the processor could run based on how many cores were being utilized at any particular moment. With all 6 cores (12 threads) active I have reduced speed down to 3.8 GHz. 5 cores is limited to 4 GHz, 4 cores 4.2 GHz and so on.
The difference is profound. 95 percent of all stutters and hiccups are completely gone, and what little is left only occurs in really scenery dense areas and high demands. CPU temps are hovering in the 80’s with an occasional momentary spike to 90, but temps never get high enough to cause thermal throttling. It’s the best it’s ever been over the last year and a half, and I could make it better if I didn’t want to push the limits of resolution. Overall I’m ecstatic with the outcome.
Thanks everyone for all of the help and suggestions!
