Hello,

We are investigating what could be causing this. Proving to be quite difficult as many have reported increase in performance. 

Thank you 

So please have the team reach out to us so we can help and provide more information and help test.

@Eddie Any news from the team? Thanks again!

Just tried version 1.1.1 and it was terrible. FPS bad but became worse and worse.  Seems to be maxing out VRAM.  At one point I had 19FPS with 83% VRAM usage but only about 13% CPU and 20% GPU usage.  When approaching top of descent I was trying to insert my arrival into the flight plan and then it completely crashed - yellow lines all over the ND, nothing responsive.  Then the plane started pitching up and down randomly although it was showing level flight in the PFD.  Tried ending and respawning 3 times, each time the same thing happened when I tried to edit the flight plan with the arrival.

I am also getting the stutters every couple of seconds and also getting a huge lag spike on landing with this current update. It is extremely disappointing to do a long haul flight and have the aircraft become unresponsive due to lag on landing. Hope we can get a fix for this ASAP.

I have specs very close to yours; I have an Intel processor but getting same issues as you. Getting stutters in the cock pit, did a long haul flight from KMSP to PHOG and it was a stutter mess when I landed. I was using the reduct textures as well. This is in MSFS 24

Hello,

We are actively looking into what is causing such performance loss for some users. It is unfortunately a pain to diagnose. We are however hopeful we're making progress. I apologise if you feel that isn't the case but I am hoping you trust that we are doing our best to make you happy. 🙂

That's the performance for me after a 12 hour flight. It's the A35K with the Qatar Q-Suite cabin, but also every other cabin version is terrible for me.
No cabin version is better but still underperforming compared to other planes.

Thanks for letting us know. If there is anything you need to help, let me know and I will find it. Couple other things that might help, the aircraft wont preview the livery in FS24. That started 2 updates ago as well. On the last update, I did the update then did a flight in a different plane, came back into the manager to install scenery and it was saying i needed to update again. I uninstalled and reinstalled instead, didnt change anything on the perforamce side though.

I've also encountered this issue. My setup isn't top-tier, but it's perfectly capable of a smooth flight. I was very happy with my flights before the recent updates, but with each new version, the performance has gotten worse. The latest version of the A350 has the lowest frame rate I've ever experienced. I even doubt if it can complete a full flight (at this frame rate, I'd probably have to rely on autoland). A good example of this is time acceleration. Before, I had no problem using 4x acceleration, but in the latest version, as soon as I enable 4x acceleration, the plane starts to convulse (I hope my passengers don't mind the sudden altitude drop (￣_,￣ )). Even at 2x speed, you can clearly feel the abnormal swaying of the plane, which never happened before. I really like the A350, and I hope iniBuilds can find and fix these issues. I look forward to seeing performance improvements in the next update (returning to previous levels would be great). Until then, I'll have to fly something else, as I really can't experience flying with the current frame rates (* ￣︿￣).

After the latest update the FPS performance has once again rendered the A350 unusable and back to the hangar.
