Hi,
I have a problem with the delay in communication between mobiflight and prepar3D.
I am noticing that very often the communication takes place late and it is noticed when I turn an encoder and release the same the values of the display do not stop.
I have increased the value of fsuipc as timing to the maximum but to no solution.

Obviously in a home cockpit it is not the only system standing like that of mobiflight, but in the same pc other programs are running that influence the simconnect or fsuipc as opus which gives me the connection between the various visual pc and the weather, or traffic programs like widetraffic.

I considered moving to a single PC, effectively removing all bottlenecks such as the LAN, opus and traffic, but I did not notice any improvement.
Obviously in my PC I don't have very high frames, but I have optimized the machine in such a way as to have constant frames at 30fps.

I wanted to ask is this a fsuipc problem? if yes how does it solve? or do I have to consider anything else like the not really high frames of prepar, fsuipc latency, simconnect, usb sockets etc etc? thanks again for the support

Simone

First Aid....

Check if "Logging Mode" disiabled.

1. Logging Mode is only to find issues..... A Active logging mode result in massiv delays while regular usage. Not shown on buttons but extremly on Encoders/Displays.
Simply disable logging.... This should help

2. Get sure you think correct for FSUIPC Polling rate.... the "lowest" value is the most fast setting..... NOT the "highest" ! Normaly 200 or 300 is recomend for most systems !

About System.
P3D is already based on FSX and get in trouble in case its not realy optimized in the basic system for current PC´s. ( Whatever its 1000 times better then FSX)
Also a couple of AddOn´s additional slow down the system.
For advanced Cockpits its basicly recommend to outsource as much as possible over the Network. For example Planing Software, Wether AddOns and so can be handle easy on other PC´s. But for normal systems this should be no real problem.
A good hint to speedup the sim is a M.2 SSD with a real 4 lane PCIe Port. Also get sure only the Sim is on this SSD so Windows is seperate.

Good Luck !
