A320neo V2 FPS drops 40% when enabling FSUIPC7

[lfrivera]

Hello, 

Without activating FSUIPC I get arround 70-80 FPS with the A320 v2. However, when I start FSUIPC (to do online flying) my FPS immediately drop to around 35-45 FPS.

Please note that I tried with several other airplanes like the PMDG, LVFR, Horizon to see if there is any kind of impact with/without FSUPIC but there isn't. I got the same FPS in both scenarios. 

Can you please help me to fix this issue with the A320? Perhaps this is due to a bad config setting or something like that?

I'm on SU15. Currently using FSUIPC7 v7.4.13

My PC if helps: Ryzen 7 7800X3D, 32GB DDR5,  7900XTX 24GB.

 

FSUIPC7 enabled (41FPS)

FSUIPC7 disabled (73FPS). 

Thanks for your help.

This sounds very strange... Is this the new A320Neo Enhanced (free add-on) released in SU15? If so, I haven't installed this yet - will install and take a look here to see if I get the same.

Could you show me / attach your FSUIPC7.log and FSUIPC7.ini files.  They should be quite small but you will have a very low upload limit as you are new to the forum (it will increase the more you post), so you may need to compress/zip them first.

Btw, those pictures are pretty useless - they don't show anything (I can't see what those boxes are never mind read the numbers!). For FPS monitoring, activate the MSFS Display FPS option, under the Debug menu (you need to activate developer tools for this).

I just installed and tested this aircraft here (on my development laptop), just sitting on the runway at EGLL and I get a very low framerate for this aircraft - only around 16. If I start FSUIPC, this drops to 13, so I do get a drop of 3fps which is more than expected, but nothing like the 30-40 FPS drop that you see. I will also check on my flight PC later.

This aircraft does seem to emit a lot of events when it is just sitting there doing nothing - mainly STEERING_SET, NOSE_WHEEL_STEERING_LIMIT_SET, LIGHT_POTENTIOMETER_SET and various LIGHT_POTENTIOMETER_x_SET events, and it even events like these lights ones that are emitted every 70-80ms or so:

And there are about 1600 of these every second. This may account for a drop by a couple of FPS I guess, but no more.

Anyway, show me your logs and also test with the MSFS FPS monitor and tell me what you see there (no need for pictures!).

Which clients do you use with FSUIPC7? Do you get the same FPS with FSUIPC7 and the client programs you use running as when FSUIPC7 is running but not any client programs?

@John Dowson Hello John. 

Please find attached the FSUIPC7.log and FSUIPC7.ini files.

Regarding your question about the plane. Is the inibuilds A320. What they call the A320 v2 which came with SU15. 

I don't know exactly what you mean by which clients. I just downloaded and installed FSUIPC7 from FSUIPC7 v7.4.13. Nothing more. I use it to start IVAO's altitude. However, this happens without running any other tool, just starting flight + FSUIPC in the background. 

Today I've tried changing DX11/12, playing with graphic settings. Same result. As I said is strange cause only happens with the A320v2, I can use any other plane and FPS are the same. 

With FUIPC running in the BG:

After opening task manager and closing FSUIPC7 task:

FSUIPC7.ini FSUIPC7.log

Can you disable the starting of the MSFS2020_AutoFPS.exe program and re-test without  that being started (just put a ; before the RunIf.
I don't expect this to make much of a difference but worth a try.

If you get the same performance drop, can you disable the WAPI (Add-ons->WAPI->Disable) and see if that makes any difference. Also try re-starting after this change.

Otherwise I have no idea why you get such a drastic drop in FPS. Looks like the main thread use is doing a lot more work. and also the GPU which I don't understand (FSUIPC does not use the GPU) - this may be due to the MSFS2020_AutoFPS.exe program.

You could also try moving FSUIPC7 off of the main core, core 1, using the ThreadAffinityMask ini parameter. You would need to calculate the affinity mask to use for your system (online tools available for this).

Other than that, I am not sure what I can do about this if this is only affecting the one aircraft. I will take a look on my flight PC to see what the performance is like there later today or over the weekend.

Did you try any of the above?

I have tested there now and get the same - a drop of roughly 3fps, so I really can't understand why you are seeing such a drastic drop in FPS when using this aircraft.

I also tried switching to use VSYNC (at 50% monitor refresh rate) and I get a steady 30 FPS with or without FSUIPC running.
