The holy grail...

This is really strange, and I have never done it before, but I noticed that MSFS tends to use just two cores / threads really heavily, even in DX12.  The other threads tend to just tick along.

So from the bios, I have disabled hyperthreading, and also deactivated all but 4 of the E-cores (just to run a few background processes).

I have found my performance in the sim is unchanged, still silky smooth, but my temperatures are a lot lower, so should stop any thermal throttling!

Your experience may vary of course, but one other benefit of this, is that I have heard the cache memory from disabled cores get share out amongst the active cores.  As we know by the AMD X3D chip results, MSFS responds massively to extra CPU cache.

Judging by what the task manager performance tab is telling me, other than the two main threads, the others don't do a lot and they are bumbling along at about 25-30%. 
So the next time I go into my bios (I don't like messing about a lot as it takes time), I am going for just 4 P-cores, and only 2 E-cores, to see what effect that has.  If the rumours are true, that should double the P-core cache.
Seems like MSFS is still very much single thread (main core) limited as we know.  If anything goes backwards, no problem, a simple reboot and back into the bios will put it back, so nothing to lose.

I disabled hyperthreading on my old cpu, but I did go all out this time on a cpu because I'm doing some other things on this pc now. So for now ill leave it and try cure the high temps, its actually no throttling as of yet but jumping around and fluctuating.

I'm suspecting because my h100x isn't made to sit on the LGA1700 mobos it could be seated poorly no matter how good its caught on. I could be wrong but lets see how the new AIO goes... I hear the 13900k runs hot as is.

Which leads me to believe that the 3090ti is to all intents and purposes pretty much the equal of the 4090,

It’s not, the 4090 is smoother and ever so faster. But the frame generation shouldn’t be under appreciated as it is by some in here I feel. It’s magical. It’s worth the entry cost of the 4090 alone…!

Now it may be that a consistent 120fps really does feel that much smoother than 60 - I'm sure @Ianrivaldosmith would say so,

It’s not that it just feels smoother, it’s the feeling of speed you get. It’s fluid. Hard to put it in to words…

Has anyone experienced a massive frame rate hit, like a 5 second pause, when the static aircraft loads?  Say, within a few miles from landing?  I get this huge pause, a TCAS “traffic, traffic” alert, then the pause goes away.

Just landed at LIRF rw 34R.

My front view server was completely smooth. The left view client had a lot of stutters. That was on approach with the coastline and airport with AI traffic also showing left.

Did a test and indeed when the server was looking left the load was extremely high.

When coming from the north and landing on 16L/R no issues at all.

The left view client should be powerful enough as making circles over Istanbul at 3000 ft with 3 major airports and AI ac it is showing no stutters

I remember when John Vennema, the President of Orbx, stated that P3D could handle anything you could throw at it, given the right hardware.

Seems that little has changed.. 🙂

Whenever I think back over the past 40 year of flight simulation, the first thing I always think of is how much hardware I've thrown at it over the years. Perfectly good PCs replaced simply because a new one would run FS a little better.

It's comforting to know that it will only take one more used car's worth to get me there. 🙃

It is true!  But then what else would we do, and what else would we spend our hard up cash on?

Just tried four P-cores.  No good. They are over-worked and topping out at 100% (really cool though at 76C).  It introduced slight stutters and lags in the scenery tiles loading in the distance. 

Going for 6 P-cores now as the temp gains are good without hyperthreading and some cores turned off.

To Ian @Ianrivaldosmith sorry for going a bit off topic.  Well done on your PC and I am glad you are happy.  Like you, I intend to go 4090 and AMD 7 series X3D next year.

I have an AMD XMD (I think it’s called that!) set in the bios to II, so it just does it all for me. Goes to about 5.7ghz under load and around 4.5 when idling. 

Blimey, that's nice to think you can get to that speed without having to faff around with overclocking manually.

I went AMD 7950X to upgrade to X3D cpu early next year. At the moment, now I can not see the point… this sim should not need any new hardware now. (Waiting for Ray tracing to release….! New rabbit hole :-D)

For me I enjoyed the tweaking. Now, that element is removed as it is no longer needed…. What do I fill my time with now?! Hmmm

I don’t think this will go away completely any time soon, regardless of hardware. The odd stutters during the approach to land phase at more complex airports are induced when the sim loads in all the airport details based on both your LOD settings and those set by the scenery dev. Once that loads, the smoothness returns. If too many objects are being called to draw simultaneously on the approach, like ground vehicles, general airport clutter, AI aircraft, terminal interiors etc, there is a momentary spike demand on the system. Stutter is the result.

Yes I'm also guessing it might not however it's plausible that at some point the hardware may overcome this.

It is easy to obtain 4k 60fps now in the sim with the newer hardware available

Which hardware delivers 4K 60fps in the most complex planes at the most complex terminals with all settings maxed including TLOD and we can leave Realtime Online Traffic off the table for now?   If single-thread performance still largely rules MSFS when you do single-thread benchmarks like Passmark a 13900K is only about 15% faster than my 9900K and that certainly will not deliver 4K 60fps at the most complex terminals with all settings maxed including TLOD, not even close.

It totally trashes any money we spend on hardware (sometimes thousands as we know), and is a bit disrespectful or uncaring really. 
But that's fine - if I get my fingers burnt, I vote with my wallet after that! 

That's right--already have perfectly smooth with these kinds of near zero frametime variance which equate to absolute perfect animation even at frame rates of 30-40, but the scenery-loading, server issues, etc won't be overcome w/ $5000+ worth of new hardware is what is being suggested here, hence the trashing ensues.
