Hi, I have found FSUIPC will cause stutters across FS9 and FSX and almost certainly P3D although I could not test in this sim. Anyone can try this in any of these sims by looking at the areas of their sim that causes most stutters. Note the stutters that you have and then try the same situation without FSUIPC installed. I tested mostly in FS9 on Win 10 and Win 7. I understand FS9 is no longer supported but I feel the issue is likely carried through all FSUIPC versions. A fix for one version would likely be a fix for all versions and easy to implement to all sims once the core problem was found. I found you can install a default FS9 and it will run completely smooth. If you install FSUIPC and nothing else, you will now have stutters in your sim. Registered or non registered FSUIPC versions both behave the same. I also found from a quick test FSUIPC appears to function fine on a Win XP install. This XP test wasn't comprehensive but indications certainly appeared to be as such. I'm thinking the issue may possibly be related to flight sims/FSUIPC running under 64bit versions of Windows? There have been other threads in the past on this and I recently also received confirmations from other users of my findings. The topic below is a typical example of a past thread: I hope this can be looked at and hopefully addressed. FSUIPC is a critical component and something almost all FS users need to run.
