Terrible performance in SU3

[Fornax]

A350 been terrible performance wise in whole su3 + su3beta period.

SU2 80-90fps (all fps with 2xFG) parked at (most) airports (no injected traffic etc).

SU3 gives me 50fps. Thats 25fps with no FG!

Fenix, Pmdg's, iFly around 100fps.

Cleared wasm, nvidia cache etc etc.

Time to do some performance optimization ini. Shelved it for now.

Feel free to merge this post with apropriate thread, but strangely didn't find any.

5090, 7900x3d, 64gb ram, 4k(5120x1440), 2xFG, TAA, Ultra-High settings.

Hello Dear Fornax 

i confirm bad performance with A350 after SU3 update , Fps Droop from 80 to 50 

@iniBuilds any Help 

I don’t have any problems with other addons like PMDG and Fenix.

You have beefer PC than me and I have 70-90FPS with 2xFG on 4k Ultra so that may not be as easy as "optimize it"

@Xenon341 With SU3, you get good performance ? 

[Xenon341]

I have decent perf yes but if I check the official forums a lot of people have perf issue in SU3, not necessary with A350.

Mainthread seems to be a big one https://forums.flightsimulator.com/t/mainthread-loads-up-more-and-more-and-doesnt-recover/729018/184

 

To be clear I would not say no to more FPS 😄 but even OP said that in SU2 it was OK and in SU3 it's not anymore but the plane did not change so for me, the platform brought some stuff that maybe don't work well.

If ini can fix some stuff that great but IMHO, something from the platform may have caused this.

Tryed to use the special downsized textures (installer) today.... 
At the beginning of the session, I think its better, but after 2 hours, it went very worse..... frames dropped to 2o-25 ... 
Impossible to do longhaules.....

Reinstalled 2024. Reinstalled A350. Cleared WASM.

Seemed to have helped actually. Still more demanding than any other AC, but performance wise(fps), its closer to SU2 now.

Still those Asobo bugs, as Xenon mentioned, - mainthread load up, just going to meny/controls degrades performance etc...

I have some huge performance issues with this plane since SU3 which have nothing to with the performance degradation mentioned earlier. For this test I just took off at an empty airport (MKS LSZH) and flew out in a straight line over the alps. 

Baseline performance on the runway is borderline for my perf target of 80FPS, but still reasonable considering the scenery and city around it.

Once I take off it becomes problematic then. It starts stuttering hugely and dropping, but only intermittently. The lowest I have seen was below 20 FPS with FG! And it always show in huge spikes in Main Thread, Manipulators and CoherentGT. I already tried clearing WASM, but to no avail.
