I'm on latest exp version, SU10 with latest nvidia driver (i think studio one, 517.4 or something)..

Every few secs, fps drops from 30 (locked) to 22 and then back.. maybe every 10-15 secs it happens.. only happens with FBW.. used to think it was a conflict with ambitious pushback.. disabled it.. only using gsx now.. still happens.. doesn't happen on any other plane including pmdg.. 

Does this happen on stable/dev version? will i be losing too many features going to stable?

im also using simbridge and remote mcdu if that helps.. not using any AI traffic.. remote fmc's work fine with crj and pmdg w/o any fps drop.. 

Anybody else experiencing this?  I’m trying to get some help from their discord too but too many voices there that drown out my issue. Figured my chances were better here.

Does this happen in every phase of flight? (ground, cruise level etc.). If so, it's likely an external source, so either Simbridge trying to connect repeatedly or Windows defender (or any other anti virus) scanning some processes.
Also you said you "disabled" the Toolbar Pushback. You need to delete it from the community folder or else it might still have deteriorating effects (it has a memory leak since March 2022 and has basically been abandoned since then).

I deleted pushback tool from my community folder.. did a test flight this morning.. sadly, the fps drops are still there..

its very annoying jerky feeling every 30 secs or so.. reminds me of p3d/fsx days.. and it only happens with fbw.. no other plane..

seems to happen in dev version too.. working with devs on discord now.. no breakthrough so far..

I am not flying ( at the moment ) the FBW anymore -  unfortunately, don't matter what i use, Stable,Dev or Experimentel i have this here and there suttering very often and if you are at a relative big Airport it is just horrible..

I think that whole plane have to be overworked about the code ( but i am not shure, no programmer here ) don't makes fun anymore to me this Airplane,  sorry to say..

Maybe all that MSFS updates have changed some things, the plane was very good at first but now..

And NO, my Sim settings are realy moderate only one is Ultra and the most is at middle settings so this could not be the problem.

cheers 😉

Ya the devs on discord say that few users have this issue no matter dev or exp version. It was there in su9 and still there in su10. Will have to ground this aircraft for a while again and hopefully things improve in the long run. It may seem like a minor thing but if this is the only plane in a large fleet of planes that’s doing this, you tend to look at other options. 
 

it was great last year and it was the only one I was flying all the time. Now with all the other payware addons we have more choices. 

I think the FBW guys are goeing over this and fixing things, but shure this takes some time..

cheers 😉

It is indeed sad to experience these stutters with the FBW. They destroy the immersion and are especially annoying during takeoff or landing.

I have them in the dev and exp version. Frames drop randomly by 50% resulting in a severe stutter. Main thread is then in the red.

By contrast, PMG 737 (and other demanding airplanes) is butter smooth. Thus there must be something in the FBW code that conflicts with something.

Hope that it will be addressed as it appears that some more users are affected.
