I guess it won’t break anything testing different options. Just wondering why you took MSFS off all the HT-threads though. How would that improve performance, when the sim has 8 performance-threads instead of 16? Or perhaps the reasoning is that you make 8 P-“threads” available for other apps? But then again, when I check Lasso with the sim running, it’s rare that another app is using more than 5% of the CPU. 

Core0 I can sort of understand, if this is indeed the thread most used by the operating system. I don’t have any in-depth knowledge of how this works. 

Because I've previously seen a recommendation to disable hyper threading overall and this is a way of doing so just for MSFS. I'm going to test more, but it did feel like performance loads were handled better.

HT adds to the energy needed per core and, hence, the heat and, in turn, the risk of throttling.  

That price might be worth paying in some edge cases where the performance of your main application scales more-or-less directly with the available thread count. 

But MSFS is not that kind of application: the law of diminishing returns on thread numbers kicks in at about 4 or 5. For MSFS, the clock speed is more important and since this is threatened by energy use (throttling) it is usually best to turn off HT when your main application is MSFS. A modern CPU has more than enough “real” cores for MSFS not to benefit from having extra “virtual” ones.

(Having said all of that, tbh as I recall it makes hardly any difference when tested with Capframex).

Yeah but all that jibberish on YouTube is just teenage clickbait!

Here’s what actually happens if I compare the results with and without all the BS in the first video.

Five tests using Capframex under identical settings at EGLL in the Fenix at stand 512:

Before all the fiddling around:

So in your case about + 1,5 fps with PL running.

What about the smoothness, as that is more important?

I have HT disabled on both my 13600K and 13900K cpu.

13900K running at 5,3-5,5 Ghz

13600K running at 5,0 GHz

I've tested with and without setting up Process Lasso on my 14900/4090 system and also tested with and without HT.

I saw no noticeable difference between setting up Process Lasso and using the CPU sets and assigning everything to the E cores and the sim to the P cores.
Turning off HT introduced a bunch of stutters.

HT on/off for improvements differ per system.

No not even that 🙂 imo: at 90+ fps, such small differences can’t support any inference of a causal relationship with any change in the settings. You’d need something much more striking to exclude changes caused by random stuff that you can’t sensibly control (eg, CPU running hotter, exact fragmentation of data in RAM, blah blah blah). 

Smoothness: the lowest 0.2% frame rate is a good measure of “smoothness” and the change is actually negative (although, again, too small to support any inference of a causal relationship).

Smoothness as a matter of perception: nope no change.

Yes it’s mostly snake oil sadly. 

HT is a weird one though: wouldn’t expect turning it off to create more stutters with your specs. Worth trying a few times to see if it’s a consistent issue or just “one of those things”?? 

Just wondering if the Affinity feature might be of a use as beside MSFS I have 11 extra addons running, verifying from multiple home cockpit software like Prosim Cockpit suite to PSXT Live Traffic..

All of the addons on the E cores .

That was my big thing...  When I was running MSFS on it's own I had zero need for PL. Hence why I've gone so long without it since migrating from P3D. 

 Now with 7 or 8 apps now competing with MSFS segmenting MSFS and all the ancillary apps seems to have improved the fluidity and smoothness within the sim for me.  

So I do think that the more apps you have running alongside MSFS the more benefit you are likely to see but as always your mileage may vary.

ProcessLasso is certainly not snake oil though,  it's been around for years and was extremely useful with P3D and myself personally am now seeing a benefit of MSFS. I would disagree with that sentiment. 

I also wouldn't expect much change with a 14900/4090, that system should swallow just about anything whole LOL.

Hm fair enough you might have a point there 😝

Good point !

I will put all addons on the E cores . Sometimes when my 2DOF flight seat is moving I get a small stutter in MSFS. If it cannot “touch” MSFS (P cores) then that would already be a good thing.

for me PL reduced sim loading time by about 2 min, it was 5 min plus, now it is 3min plus, long pauses when reaching large 3rd party airports is significantly shortened.

smoothness over all is much better during taxi, take off and landings (except for large airports loading as mentioned above.

Inveterate tinkerer… I guess I belong to that group 😆 

Been using Lasso for years, way before MSFS. I’ve set MSFS to high priority and assigned most apps that I use along with the sim to the E-Cores. Not a very complicated setup.

EDIT: After watching Island's video, I'll make some changes, including not having MSFS run in any CPU priority mode. 

God bless the tinkerer's, their tinkering helps out the non tinkerer's so the non tinkerer's dont have to tinker

5,5, that’s a very nice overclock. I think I’ll try without HT too. I’ve always thought that the more threads, the better. But I remember that previously (before MSFS) that I actually turned HT off to achieve a higher overclock.

Or I might just turn off HT, reduce the Vcore and get better temps.
