Weird intermittent FPS drop

Featured Replies

I repeated the exact same flight as yesterday which had sim ending FPS degradation.

Everything worked flawlessly today.

Yesterday’s flight was the first time I had ever experienced that problem.

I had massive issues.  Started out fine. An hour into the flight from DEN to ORD with the captain sim 777 this happened. I noticed panning was getting stuttery about 45 min in and buy an hour I had to just shut it down.  I was averaging 15 FPS with massive stutters. Normally, I'm running right around 60 at cruise. Any time I panned there were second plus delays with massive stutters and fps falling into the single digits.  The live weather was not working at any point today, skies were clear.  AIG was running but turning off AIG and Live weather... that did nothing, frames stayed the same.  I reverted to 466.77 drivers for my RTX 2070 S which fixed the screen tearing and pixelated light casting issues, but I don't think the driver revert is causing the issue.  Given that people are experiencing the same I'll bet it's related to servers.  This sim is broken.

Yesterday I tried to start a flight with live weather off from the very beginning. The issue persisted. Massive FPS drop a few minutes after the launch making sim virtually unplayable. Today I'll try to test it with all online functionality switched off, but then again I can't possibly imagine flying this way even if it works. So yeah, it is broken. 

Same thing happens to me with my last flight, it massive kicked in at around the TOD , after coming down near my landing Airport it realy was unplayable, stutters all over the place i do not know i had something like that before, i just try to Land to see what happens but it was a freaken stutterfest..

cheers 😉

At first I was unsure if it was that the flights I was trying were way longer than my usual schedule, but, yes, massive performance degradation is a thing now in FS. Stutterfest and eventually even a CTD.

The weirdest thing in my case is that I don't get to perform any flight, longer or shorter anymore. Fps degradation starts at a very early stage, usually while I'm still sitting on the tarmac, not even moving. I wonder if the same thing happens to you guys, it's just that you have much more powerful rigs than my 3070 and you just don't realise it so fast, until it drops even more so it becomes visible on even stronger GPUs.

 To report back:

I did another  2 hours flight today with the FBW A320 and all was normal.

After started the Simulator i was goeing first to the Option menü and set my Live Weather from on to off.

Than i did everthing else. I am not shure that this is the 100% Solution to the problem but worked for me with this flight.

From now on Live Weather stays off ( for me ) until this weather thing is fixed by Asobo at some update.

Asobo did implement some fix apparently. Well, it didn't help my case. I cleared my community folder, spawned with default Cessna at a default airport. Five minutes and that's it. Fps drop and there's nothing I can do about it. This is getting ridiculous.

 

edit: I managed to capture the exact moment of dreaded fps drop occurrence. Oddly enough, it happens almost exactly at the same time after launch.https://vimeo.com/662072081

Necro thread, but it shows up high enough on Google to maybe warrant a response. 

Updating FSUIPC fixed this issue for me, but not before downloading ISLC, which you should be able to find with a Google of ISLC with MSFS.

 

Good luck if you see this in the future!
