We're getting off topic, but my advice is to move away from the idea that you need to tweak everything. This isn't FSX, LM built their sim engine for modern, multithreaded hardware.

If you have hyperthreading, leave it on. Turning off hyperthreading only makes sense if you're pushing for an extreme overclock. A stable, moderate overclock is what you want here.

TL;DR  Keep it simple. The only "tweak" that reliably improves performance is new hardware!

Pretty bad advice. I have a 9900KS water cooled at 5GhZ. With HT on I get stutters, long frames, whatever you want to call them. If I add an AM I can eliminate 90% of the stutters.

Bad advice? Your opinion is based on your single install, and there was clearly a serious problem with either this or your system (or you are just obsessed with stutters). Some of your selected recent comments on the matter:

• "Spot on, the problem is the software. The mirage of endless ‘solutions’ in here comical. "
• "All of this work. Did it ever occur to anyone, maybe, just maybe, the sim itself is just ‘broke’? Don’t have this problem with other sims."
• "A quick google search will show you a decade worth of posts relating to stutters and hitches and whatever else you want to call them. They exist, and they are prevalent. "
• "If I place ALL of the P3DV5 sliders at minimum, the sim is still OLD. It still has problems with ground textures morphing (try Madeira full default sim with low sliders and see for yourself). It stutters and chugs along.  It is not designed for modern architecture. Sure it might have been switched to DX12, however it is STILL the same old sim engine, that stutters and morphs along. Go check out P3Dv% forum over at LM and see for yourself! It's like putting a new Porsche engine in an old Ford Galaxy."
• "FPS is not a problem here for me. The problem is stutters over large cities. Only happens over large cities too. (Especially London). Also popping scenery. It’s as if the sim can’t keep up with my system! It’s trying to load things too slowly."
• "A bit like orbx then. Those sceneries cause stutter too. Regardless of FPS, they just don’t push the scenery through fast enough. Popping and stuttering in dense areas."

You're also determined that X-Plane does not stutter:

• "XP-11 is a far newer engine, and with Vulkan the smoothness is far superior to P3DV5. Also P3DV5 costs a small fortune to get it looking good. I prefer XP11 for the actual feel of flight, and not having to fight stutters (they simply don't exist) "
• "One thing xplane has going for it, is zero stuttering, fluid flight."
• "Yup, one of the reasons XP holds my attention more, stutters like that, that just can’t seem to be rid of, even in P3DV5, where they are greatly reduced, they’re still there."

If your reports of severe stutters to point of having an unusable sim are correct, you are dealing with a highly atypical situation. The issue here is getting the last little bit of smoothness and performance from the sim, which is what HT on/off and affinity masks are trying to do. The differences between these approaches are subtle enough that experienced simmers can still argue about whether they work or not after many years of testing and discussion.

For new users - the problem is that people may think that they need to tweak, add affinity masks, disable CPU features etc to run the sim. Prepar3d has not been designed for this, and to the best of my knowledge disabling HT is not something that LM recommends. You do not need to do it, and if it scares you, then rest assured that this sort of thing is highly optional.

For the tweakers in the room, go crazy. I do run an affinity mask, but I have zero evidence that it helps, so if there is a performance gain it is subtle. On some systems, changes to HT or broader affinity mask changes may help (or hinder) to a greater extent.

If your sim is near-unusable with HT on, that's another issue altogether, and I think all the posts that I've seen stating the problem to this extent have come from you.

I have HT on and AF set but don’t have micro-stutters and only the occasional stutter. What resolution? What frequency is your monitor set to? Is Core 0 maxed out?

I run at 3840*2160@30Hz. Core 0 is nearly always below 100% except at busy airports like EGLL, LFPG etc. I accept that in order to see plenty of Ai.

All come from me? Your delusion level runs so high that I won’t even respond to you other than to say, morphing terrain and stutters are PREVALENT in the P3D runs from 1 through 5. Go read the LM forum and you’ll see. Even better, Google it. 
Goodbye.

Took your advice and googled it - key word search "stuttering" + "texture morphing"

First hit. from elsewhere on the web:

This is a known issue I believe. I too posted about it a month or so ago, when P3DV5 came out. Apparently there is nothing you can do about it. Various YouTube videos show this too. To really see it happen, try flying around the island of Madeira. That’s when it’s at its worst. The advice I was given? Don’t fly in Madeira.... yup!

Add this to the stuttering game engine and you have =
Immersion killer! For IFR pilots, maybe they turn a blind eye. For VFR, it destroys the sim!"

I was also saddened to get an Axis I diagnosis of "delusional" from you, but then I remembered that you gave all of the guys over at the .org an Axis II diagnosis:

"One doesn’t get much help from the narcissists over there. You have to dig through posts and beg."

I think you're overdoing the amateur psychiatric diagnoses!

See you around.

Ok, I’ll do it for you. Seen as though you can’t run a generic search term.

This is an issue all current and future flight simulators are suffering from.. the key is who hides this issue best..

Do you understand why this occurs? The world around you cannot be loaded ahead of the entire scene as normal video games do.

So all flight simulators requires the world being rendered as you move along. It doesn't matter where you store such “world", local disk or cloud (streaming) or which format the same problem is present. The world will need to be rendered as you move and the faster you move, more resources are required to render such world.

Local disk has limited resources and streaming as well as it depends on your capacity to stream.

So the problem cannot be solved at this point in time until different technologies are available that allows the rendering to be done more efficiently.

Unity engine V5 looks very promising on this area, but it will take a while for this new technology to be fully operational and implemented by flight simulators.

For me the texture morphing it is unacceptable, this breaks the immersion in the simulator.

Hey Simbol -- don't forget that a (userIanrivaldosmith) knows more than a developer :) /s

Keep up the good work!

You I get it, however I am sure they could hide it a bit better in P3DV5, like some other sims do.
