Major performance deterioration at altitude over Europe?

Recommended Posts

Two days in a row, EHAM > EDDM, up at cruise altitude major stutters to downright pauses.  All the way to altitude all was great with very low CPU use, core temps around 50C, GPU coasting along at 40% utilization, but this sudden deterioration.  Had to abort both flights.  

Anyone else?  I also just installed 4090 so wondered if maybe its frame generation routine was hosed as a cause for this, but I have to doubt that I have had success in US flights.

Photogrammetry is in, FWIW

I've also noticed higher CPU load at higher altitudes, even nasty red spikes, it's very strange when it should be the other way around.

Btw, i'm in Beta.

The same happened to me in the last flight I did, EGGW - HESX with the FBW A32NX and latest MSFS stable version. During cruise over continental Europe I had very high CPU usage spikes without any reason, causing stuttering. As soon as I left behind Greece going into the Mediterranean sea, those spikes stopped.

I just had a CTD, flying Asobo B747-8i from KIAD to EDDF. Around EHAM or there abouts. I can't even remember when I had the last CTD and now this. And with a default aircraft! No beta, not many add-ons, flying with FSHud.

Europe is full of urban areas and full of photogrammetry. The loading in from the servers and the memory usage become very high in these circumstances. Your CPU and GPU won‘t matter, because it‘s basically all about a download stream from the server.
You can test this very easily: Fly from western England to the east. You‘ll get FPS drops and stutters right up until you are over the North Sea. Then it‘s all good suddenly (memory is cleared, download streams stop).
Turning PG off will solve most if not all of those problems, if this is an option for you.

Thanks that makes some sense except that I've had so many flights over Europe without this, so therein lies the puzzle.  But maybe their servers or are more impacted now than in the recent past.  I will just plan on leaving PG off then while flying in this area.

Cheers and thanks again!

Thanks y'all this is reassuring to me at least.  Of note, the FBW 320nx has really taken a turn for the worse, but I have no idea why it's a plane I use frequently.  Both latest Dev version and Stable are the same, and I wondered if it was something to do w/ my new 4090, but I don't think it is it's some other change with that plane, and fairly recent at that.

Also had major stutters over the alps coming into Venice FBW A320 tonight. It felt like a fuul blown pause at some points.

Never experienced anything like it in 4 years

Yes. And sadly not any different in SU15 so far...

Could this be another windows update issue.

Will try the same route tomorrow with the B2 Fenix and see what happens.

No it's likely a server issue, as I explained above:

I noticed a dramatic loss of performance over Germany when heading towards the Belgian border earlier. Photogrammetry already inactive.
