[1.4.11.0] Main and/or render thread maximizes on landing at airports

Did another flight:

same as above in settings and aircraft.
Route: LOWI - LFPG (both default airports)

Taking off from LOWI and the entire route to LFPG, very smooth performance.

Landing at LFPG, as soon as I started flaring, huge drop in performance.

Something I noticed:

  • seems to be related to the camera movement over the runway ?
  • Stopping the aircraft completely on the runway, performance is smooth. I can pan the cockpit camera fine.
  • Opening the pause menu, which causes the camera to move backwards, the performance tanks again. Again on resuming the flight.
  • Resuming aircraft motion, tanks performance. Stopping the aircraft again, performance back to normal.

Stopped:

Thanks for your report ! Same thing here ! Sometimes, take off experience is very good, and it is crashing down at flare. I noticed that after un hour of flight the problem begins to happen, with small stutering appearing and then going bad. Sometimes it recovers during the approach, but on the runway it is not acceptable, still you completely stop.

I will try tonight with a setting I did not touch for now : It is in the advanced power management, it seems that there is a ā€œ20 minutesā€ set to power the hard diskā€¦ Could be a possibility. I will check itā€¦

Yes i am wondering about the same!

25

after a long flight with a Airliner It stutters when landing and rolling out, this was not the case in the betas before

26

I already have it at zero I think, and besides, I am running the game on the nvme, so this shouldnā€™t be the cause of this.

But I did try with cleaning the entire shader cache as some others had suggested on a different thread and it still behaves the same.

27

Yes, I confirm that clean shader caches are not helping. It happens with it set to desactivated, or limited at 10 GB.

28

Wellā€¦ It dis not solved the problemā€¦
So Iā€™m Lost ! :slight_smile:

Again randomly just sitting at the Gate FPS plummeted in the latest Beta

All aircraft, many aircraft, a few aircraft, or just this aircraft?

31

Only in this aircraft at the moment. I do feel the performance is worse in this latest build compared to .12

32

Yeah in the latest .14, I no longer had the stutters while taking off from LFMN, but now Iā€™m having a lot of micro-stutters just at the gate. Started with no stutters, then for some reason VRAM usage increased and just at the limit of available VRAM and then micro stutters all over the place. Just when I got to the runway, smooth performance.

Medium overall settings, itā€™s incredibly bad on performance if I try to run High overall or anything like that, which is baffling as I am running 4070 Super, which, I understand that nVidia is screwing everyone over, but if itā€™s this bad on performance with 12GB of VRAM, I wonder what everyone else with less is experiencing.

33

Having severe stutter at cruise alt in .14 on the second flight.. CPU spikes every 5 sec to above 85% which results in a whole PC leg. Mouse, YT vid and discord i.e. R7 7800x3d @ 45 degree celsius WC, RX7900xtx 64Gb ram 6000mhz

Your VRAM is maxed out.
