FSUIPC 7.4.16 causing micro stuters

Hi All,

  So noticed that my sim is stuttering and I'm noticing big CPU spikes every few seconds.  When I kill FSUIPC the stuttering stops and the sim becomes smooth again.  I am running 7.4.16 with no other app sin the background.  ANy insight on this.  Happy to attach some log files if you can guide me on how to do so.

Does this occur with all aircraft or just one or more?

The only cause of such micro-stutters that I can think off is excessive logging by MSFS. Can you open the MSFS logging console (from the development menu - you need to switch-on devmode to see this, in the MSFS options). If you see lots of messages logged, please tell me what they say. Usually this is caused by requesting sim variables from the new Fuel or Electrical systems when using an aircraft that does not use these systems.

Also please attach your FSUIPC7.log and FSUIPC7.ini files (from your FSUIPC7 installation folder) - no additional logging needed for the time being. Make sure you exit FSUIPC7 before attaching files, and you can zip/compress them if too large to attach.

The console is repeating with the following

"[FuelSystem]Attempting to access valve with an invalid ID : (Is 10, should be 1 to 😎
[FuelSystem]Attempting to access valve with an invalid ID : (Is 9, should be 1 to 8)"

 

I used aircraft selector and changed to a few different aircraft types.  I used the FSS 175 and the Asobo 320.  Once I quit FSUIPC, these message stopped along with the stuttering and spikes.

You are adding some simvars to FSUIPC offsets using the myOffsets.txt file, and it is two of these that are causing those messages:

Quote

    93890     Adding simvar 'FUELSYSTEM VALVE OPEN:9' to offset 58D0 (size 1, type 'I32') for read-only access
    93890     Adding simvar 'FUELSYSTEM VALVE OPEN:10' to offset 58D1 (size 1, type 'I32') for read-only access

Remove those from your myOffsets.txt file, Note also that the other FUELSYSTEM variables may also give issues when using an aircraft that doesn't use the new  fuel system:

Quote

    93875     Adding simvar 'FUELSYSTEM VALVE SWITCH:3' to offset 58A0 (size 1, type 'I32') for read-only access
    93875     Adding simvar 'FUELSYSTEM PUMP SWITCH:1' to offset 58A1 (size 1, type 'I32') for read-only access
    93875     Adding simvar 'FUELSYSTEM PUMP SWITCH:2' to offset 58A2 (size 1, type 'I32') for read-only access
    93875     Adding simvar 'FUELSYSTEM PUMP SWITCH:3' to offset 58A3 (size 1, type 'I32') for read-only access
    93875     Adding simvar 'FUELSYSTEM PUMP SWITCH:4' to offset 58A4 (size 1, type 'I32') for read-only access
    93875     Adding simvar 'FUELSYSTEM PUMP SWITCH:5' to offset 58A5 (size 1, type 'I32') for read-only access
    93875     Adding simvar 'FUELSYSTEM PUMP SWITCH:6' to offset 58A6 (size 1, type 'I32') for read-only access
