If someone could confirm a slight performance optimisation in this beta I would be grateful.  Or maybe it is just the removal of something that was sapping performance before.

I can't go above 60 FPS anyway as that is all my 4k monitor can achieve, but in early testing, it didn't dip below 60, and I couldn't detect stuttering; it seemed silky smooth, with just the odd scenery loading micro-pause a few times (expected).

But the main point that stood out for me was going back through a temperature trace for the CPU. 
It is a relatively hot night in the UK tonight, but even when throwing the B787 around, my core temps never went above 87C (most were between 83-85C) - strange!   I am normally struggling to keep them under 93-94C on the 13900.
The only thing I can think of is a bit of optimisation, or removal of something that was sapping performance previously.  I am sincerely hoping it isn't a fluke!    

I have not tried DX12 yet - some people had stuttering previously so I hope that is fixed for them.

Just updated without issues as usual. Got in first time, same loading time of about 2:30 minutes, same performance.

I'm a bit confused here. The 787 flight model was not changed for SU13. Can you describe in more detail what you're referring to?

Also confused - I took her on two medium hauls today and she is just stellar and so is SU13.

A big tired of this, Nice simulator, but back to P3D 5.4.

Best.

 

Okay very relevant, thanks for telling us.

I would rather think about what BETAs are actually designed for and if you are the right person to parcipitate in such a BETA... obviously not, as you treat it like a regular update, which is NOT the case...

seem like that. just doing a first flight after many days and I am in constant 30 fps (again). so far so good. saw drops down to something like 8-12 fps in the last built, not constantly but under specific = demanding conditions. so still too early to be happy, will be landing in EDDM in almost 2 hrs and then we'll see if it keeps the 30 fps. note though I a am locked at 30 fps. don't need more but also don't want less.

For me the beta is as smooth in DX12 as its ever been. I am running 2k with an old GTX1080ti on a GSync monitor. FPS? meh - 25-50 depending. I don't care. The Worlds updates are still donwloading - my Internet is 2010 level - 25Mbits if I'm lucky. But this is UK 2023 in the countryside, so what do you expect?

I don't think memory leak is the right thing to call it, but if I fly long enough, the GPU line starts to turn red in Dev Mode. Stutters.

The flights start up fine, even in dense airports, but after a long while the same issue above seems to always happen. Closing and rebooting MSFS instantly cures the problem.

That sounds like one to report.

Stutters.

Fielder again:

I found what the problem was: fsuipc.

Task Manager, then expand flightsimulator.exe. fsuipc was underneath flightsimulator.exe. I exited fsuipc in task manager and the problem went away completely.

(It took me an hour closing stuff in Task Manager to find the culprit).

The stutters fsuipc caused were about 1 second apart, a steady stream, which always starts after an hour or two of flying. Some addon I added to MSFS uses FSUPIC and calls it up when MSFS starts. It's really that addon (whatever it is), not fsuipc itself that is the culprit.

Is that the landing rate calculator?  I had problems with that through FSUIPC. 

I got rid of it as I wasn't really using it anyway - If the wheels are still on after landing, basically I am happy!

I live on a narrow boat with a Starlink satellite dish on the roof.  I average 200Mbits, but often see 300.  Expensive, but I got fed up with 20Mbits. Latency is low enough for gaming, no problem.

I am looking into this, as they missed me for fibre, and 5G is not available yet either.

If you could let us know which add-on that is, please, it would be *incredibly useful* for everyone to know.

There have been a lot of complaints on performance degradation after 1 or 2 hours of flying. If a commonly used add-on is a culprit, it would be invaluable to know which one.

Edit:  OK.  I just saw Miguel's post.  If that is his attitude then it is a waste of time responding

Yeah, the people that dramatically insist on telling us all they’re going back to a 2006 simulator is a bit tiring. 🙄And I agree, the 787 is fantastic.
