Follow all this? Been following all this HT/AM for almost two decades and not found any conclusive evidence or end game. 🙂

Steve, May I inquire how Alder Lake on both Win 10 and Win 11 are impacted by this with the -P and -E cores and the scheduler in W11...  

Speaking as a 12700 owner 🙂

Just wondering how that changes the equation.

I see a lot of numbers and letters posted on the AM issue in this thread (even more after P3Dv5.3 added some entries in the cfg), but I wonder whether the gain (if there is any) is worth the headache. If someone comes along and writes "I have this CPU with XX cores and XX threads, what is the best AM setting for it", what does that person try to accomplish?  It sounds like there is something wrong with the default configuration. I suspect that some users believe that a certain non-default setting will magically give them a sizeable FPS boost.

I have not tinkered around with AM since P3Dv3.4 because I found out that a small gain in FPS by placing the main task outside of core0 can be lead to other unforeseen problems, like blurries. I agree that turning HT on generates more heat if the cores are loaded and that turning HT off allows you to overclock more. But don't forget that many users run other programs related to multimedia that benefit greatly from having HT on, and if doing so costs me 4% in maximum FPS, then I am willing to accept it over having to switch HT on and off each time for different applications.

Hello!
I did a complete fresh clean install to V5.3 Hotfix 2 and I'm experiencing for the first time some Micro-stutters but with nice FPS (80-90) on stock sim without addons.
It happens especially during "aggressive maneuvers" on the standard F35. I deleted everything before reinstalling but I honestly don't know what to do. I'm using the same graphics settings as previous versions when it was more smooth. 

Has anyone had this issue before?

My guess is 80-90FPS isn't sustainable.  What are they dropping to during these "aggressive maneuvers?"  Focus on your lowest FPS not your highest that's what you need to try and optimize around for fluidity.  Even if you are just going from 80-90 cap it at 80 and fluidity should improve massively. You also don't state monitor, refresh, etc etc

it all makes no odds what cpu you have, what gpu you have or whatever tweak or graph you use. 

Im currently as i type this sitting in MMMX with 15 FPS. Turn off DL,  gos upto where it needs to be.  

its the same if you fly into one of 100s of payware airports with craply done dynamic lighting (unless you get a inibuilds preset), or un optimised textures your knackered.  no matter what hf you use.  Thats the reality of this.

Ive flown into 5 airports this week where this is the issue.

sure the proformance in the new HF is good so long as you dont go into certain badly done optimised airports, and you got jack chance of the developers ever updating them as they jumped onto ms2020.  people need to open their eyes and remove the rose tinted glasses with this.

jetstream designs 

uk2000

rf scenenry 

orbx 

fsdreamteam old stuff -- lax, sdf etc etc 

aerosoft 

taxi2gate,  MMMX  horrific for example.

All these,  old outdated scenery which is pointless, unless you have remove the word not allowed dynamic lighting and unoptimised textures.

i know you lot think LM walk on water for their updates but theres a ton of scenery designed and made for a 20 year old sim, The developers know its more profitable to sell their products to the teens at ms2020 instead of flogging this dead this.

La mia ipotesi è che 80-90 FPS non siano sostenibili. A cosa stanno cadendo durante queste "manovre aggressive?" Concentrati sul tuo FPS più basso, non sul massimo, questo è ciò di cui hai bisogno per cercare di ottimizzare la fluidità. Anche se stai passando da 80-90, fallo a 80 e la fluidità dovrebbe migliorare enormemente. Inoltre, non dichiari monitor, refresh, ecc

My monitor is LG Ultragear (27gn850) 2K 144Hz. I tried to lower the refresh rate to 120, 100, 60 but same thing, for example 60Hz for me is the worst because I also see stuttering on YT and during normal use of the pc.

Using the p3d counter, the drops aren't very noticeable (for example 80 - 99 - 70 - 90 - 59) and the minimum I think was 40.
By "aggressive maneuvers" I mean pitching up and down quickly, and during tonneau stuttering occurs when the aircraft quickly returns to level flight. (I can make a video tonight if needed).
I tried every way limiting to 30fps in p3d and outside but the result was not smooth. I'm starting to think it could be related to monitor refresh rate.

Thank you!

Wow, someone got out of bed the wrong side this morning.

In the middle of a long flight, so can't check what you are saying but will look later.

That was weird. When I first read this, it was in English, reading it again 5 minutes later, it had switched to Italian.

On my setup, I actually also notice more micro-stutter, or more like nano-stutter on 5.3 HF2 than was the case with HF1. I do notice this happens when CPU is maxed on the main thread, so guess that's the explaination. What I wonder, is if HF2 in some way causes greater CPU-load on main thread in specific circumstances than was the case with HF1.

@Ray Proudfoot I wrote the original post in English, but I think during the edit for a grammar error, my Chrome translator messed up with an automatic translation to Italian. I'm sorry for the issue!

That's an interesting input...I think we are experiencing the same issue, because the nano-stutters are not very noticeable, but happening especially when flying close to terrain and/or watching the ground.

Steve, my CPU was clocked at 4.6Ghz prior to overclocking. Now running at 5.1 that represents a 10.7% increase.

If P3D takes longer to show the Scenario screen or before the sim is fully loaded that’s not really important to me because I’m working on my flight plan in PFPX on my laptop. Each to their own of course.

The file loading is happening all the time you are flying Ray so you need that to perform well. It's not about getting your sim loaded quicker, that's missing the point because that simply comes along with faster file loading.

 

Guys,

Put simply: AMs are to prevent fps loss (can't gain fps only lose it), maintain consistent fps, and finally, HT can increase file loading performance.

That's all you can do.

Yes, I understand that Steve. I haven't noticed any 'blurries' because scenery cannot be loaded quickly enough.

And because I have a 30Hz monitor and run with VSync enabled there's enough in reserve for loading.

Thanks Steve, I’ll certainly give 16215 a shot. Will need to keep an eye on the max temps reached by Core 0 assuming, that is, P3D makes use of LP1 in addition to ‘maxing’ out LP0. I am assuming that main thread activity will not be shared by the 2 LPs...or am I wrong about that?

EDIT: Actually I am wrong about that as, somewhat belatedly, I note that you have moved the three ThreadSchedulers:

00,00,00,00,00,00,01,00=MainThreadScheduler=2
00,00,00,00,00,01,00,00=RenderThreadScheduler=3
00,00,00,00,01,00,00,00=FrameWorkerThreadScheduler=4

I’m confused! So, what’s new?...lol. Could I ask you to run over again how you arrive at 2,3 and 4 for the three ThreadSchedulers in the above example, please.

Is it as simple as counting from Core 0=1, Core 2=2, Core 3=3 and Core 4=4 and the threads are placed on the Logical Processor of each of the three Cores as defined by the P3DCoreAffinityMask?

Just fired up Prepar3D and I note that the main thread is now running on LP2 and... surprise, surprise...while sitting on the rwy at 1S2, logical processor activity is holding at 80%. This looks promising!

Other activity is seen on LP4 (20%) and LP6 (10%).

LP0 (10%), LP8 (10%), LP14 (10%)

Regards,

Mike

Hi Mike,

You count the LPs (0 to 15) with ones in the P3DCoreAffinityMask from right to left:

07,06,05,04,03,02,01,00=core number
11,11,11,11,01,01,01,11=AffinityMask=65367
11,11,11,11,01,01,01,11=P3DCoreAffinityMask=65367 OR
00,11,11,11,01,01,01,11=P3DCoreAffinityMask=16215
00,00,00,00,00,00,01,00=MainThreadScheduler=2 = LP 2
00,00,00,00,00,01,00,00=RenderThreadScheduler=3 = LP4
00,00,00,00,01,00,00,00=FrameWorkerThreadScheduler=4 = LP6
 

What you see is scenery gathering on LP0 and LP1, LP2 MainThread, LP 4 RenderThread, and LP6 FrameWorker.

With that I am seeing some activity (5%) on LP3 the sister LP of the MainThread so not too bad. Flying along I see the scenery gathering hitting 100% most of the time so imagine if any of those tasks should occupy a main thread core LP you would get stutter.
