I am getting microstutters whilst using FSUIP7

[Penny93]

*** Moved to FSUIPC7 support sub-forum ***

Hello, I am using MSFS2024, and download FSUIP7 to use A Pilot's life chapter 2. I downloaded it from https://www.fsuipc.com/. I have noticed, whilst FSUIP7 is installed and running, I receive less FPS and a very stuttery experience. When not installed, the game is very smooth. I find it similar to the experience users had in this thread - 

Is setting fuel pump thing to 0 still default? Or is there something else I could perhaps try? I am sorry if I am missing info that may help, please ask for it if I missed something helpful. Appreciate you taking the time to read this, thank you!

First, please use the FSUIPC7 / MSFS support sub-forum for all issues/questions with FSUIPC7 and not the main support forum which is for all other versions/products. I have moved your post.

Yes.

The main cause of such stuttering is excessive logging by MSFS. Can you check the MSFS logging console to see what messages are logged, and if they are being logged at a very fast rate (you will need to activate Developer mode in MSFS to see the logging console).

Does this occur with all aircraft or only a selection (please try both simpler/ GA aircraft and more complex ones)? Excessive logging can be caused by FSUIPC requesting variables from the new fuel or electrical system in an aircraft that does not use them. FSUIPC does not do this by default, and so if this is the cause it is due to a simvar being requested via the myOffsets.txt file. So, if using that file, check to see if it has any such simvars added and if so you should only use that file when flying an aircraft that uses the new systems.

Please attach your FSUIPC7.log and FSUIPC7.ini files, as well as your FSUIPC_WASM.log file. Please only attach files once FSUIPC7 has exited, and only attach the WASM log file after exiting MSFS.

Hello, thank you for responding to me. Apologies for posting in the wrong area!

 

I am work right now but will check and report back regarding the logging. 

 

I have only tried it in the A321 and A320, developed by Fenix. I am unsure of other smaller planes as I only fly airliners in A Pilots Life but I can test some others. However, I didn't have this issue when using FSUIP7 whilst flying for a virtual airline and seemingly only is an issue when the data is being tracked through a pilots life. This isn't confirmed, just my experience. 

 

I am a little unfamiliar with the offsets file and how simvar requests work, or how to "not" use that file. 

 

I will send the files you requested as soon as I am home. 

 

Thank you!

Hello, here are the files you requested, except I do not see a WASM file. I also do not see a "myOffsets.txt" file

The WASM log file is under your AppData folder, but for some reason you have not installed the WASM module, so you won't have one anyway,
The myOffsets.txt file only exists if you create one.

In the log file you attached, you didn't even load an aircraft or start a flight, so there could have been no possible reduction in FPS. Please attach a log file when you experience the issue.

Did you check the MSFS logging console for messages? Please do this. Can you also try with FSUIPC7 running but without APL running, to see if the issue is with FSUIPC7 or is with APL If you get the FPS drop with FSUIPC and without APL running, you could try moving FSUIPC off of the first 2 CPU cores by using the ThreadAffinityMask ini parameter. See, for example, https://bitsum.com/tools/cpu-affinity-calculator/ on how to calculator the mask value, and then add the entry to the [General] section of your FSUIPC7.ini file. I use the following which will use cores 2-7:
   ThreadAffinityMask=xFC

During some of my initial troubleshooting, some people said not installing the "extras" stopped the stuttering issue I've been having, so I didn't install them this time around. 

Here is the log file again, whilst the reduction in FPS is occuring. FSUIPC7.log

The log doesn't appear to be generating lots of entries. Sometimes there is a burst of logs but not a consistent, fast entry of logs. 

I didn't see any difference between APL being open or not, seems the issue exists with FSUIP7.

That can have absolutely no affect whatsoever, as only additional software and files are installed with this, and nothing is actually started or used unless you manually do something with what is installed.

The log file you attached was attached when FSUIPC was still running - please exit FSUIPC before attaching files.

Did you check the MSFS logging console for messages? Did you try setting the ThreadAffinityMask?

Fair enough, I was simply troubleshooting and multple people said since they didn't install the additional stuff, the issues disappear. Didn't work on my end either way. 

My bad on the file, I will attach it again once I have finished a flight and closed FSUIP7. Although, FSUIP7 sometimes doesn't show up in task manager. 

Yeah, I reported on the MSFS logging console in my previous message. The log doesn't appear to be generating lots of entries. Sometimes there is a burst of logs but not a consistent, fast entry of logs.

I did try setting the threadaffinitymask but saw no difference.

Here is the log again, pretty much the entire flight was stuttery and laggy.
