Stuttering

Sleepy81

@usul Jupp, have had the same. And so far only happened with the Baron. Went from about 40 to 20 fps I VR, with stuttering every 1 second. A restart seamed to fix it, but worried it will happen again.

I have this problem with the A36 and the Baron. The 310 from Milviz works very well. The C172 from ASOBO too. I haven't tried all the planes. I thought it could be the TDS GNxi but with the Milviz which has two I have no problem.
I don't use the VR.

@usul

DX12 or DX11?

DX12 or DX 11 is the same

@usul I had the same issues until I updated FSUIPC...which I rarely use but still loads with MSFS. If you have FSUIPC be sure to update to latest version. That fixed it for me. There is also some posts about editing the FSUIPC.ini file by adding...NumberOfPumps=0 to the [GENERAL] section of that ini file. No idea why, but many have said that the stutters went away.

GunStrauss

@djw hmm, just out of curiosity. why do you run an extra module that you may not need?

...in general, what are FSUIPC used for these days?

@djw Thank you, I did it but it doesn't change anything

@gunstrauss I installed fsuipc after noticing the problem because for some it had solved their stuttering problem.
I think the problem is between the chair and the keyboard because it seems I am the only one to have this problem with these planes.

@usul Have you tried to remove all other Community add-ons? Just rename the current community folder or move it to a different location, move the Steam Gauge planes into an empty new Community folder. If it does not help, then uninstall all 3rd party modules.

If this solves it: Reintroduce your most beloved global add-ons and modules, until the problem re-occurs. Then report the problem to the developer(s) :) Maybe the addon causing the problem is not worth it... then permanently remove it. But still report the problem to the community for others to be able to solve a similar issue in the future...

usul

I'll try this.
Thank you.

@gunstrauss I think I was using it for Pilot2ATC

I emptied the community folder, I just left the bonanza there. Same thing.
I uninstalled FSUIPC. Same thing.
I don't understand what's going on.
I opened a ticket.
Thank for your advice.

@usul ok :/

hope you’ll find the cause!

I found big stutters in this addon until I updated FSUIPC (unregistered) and it's fixed for me. Smooth

Reply from the developer for you:

I just experienced this myself, and determined that it was due to SU12, and not the aircraft. I was able to fix this by clearing the DX12 Cache (I'm not even using DX12) using the Windows Disk Cleanup utility.

Hope that helps.

@voice-of-reason Tank you for your help.

I finally found the cause of the stuttering. It's Windows Defender. When it's disabled everything works fine, no stuttering with the Bonanza or the Baron. So I installed an antivirus configured in game mode and that replaces WD. So everything works fine.
Thank you all for your help
