FSUIPC experiment with P3dv5

Over the many years that FSUIPC has been in use, a small number of users have made similar suggestions, usually based on invalid 'tests'.  Many users do not seem to see these issues.

In P3D5 some report stutters while others claim very smooth results, but it's not always clear if FSUIPC is being used or not. Either way, if you are going to test for any effect you need to do it much more objectively.

For any route you try without FSUIPC, you need to refly it, in identical weather conditions, using the same aircraft at the same time of day, with every setting the same, while using FSUIPC. Otherwise you have nothing to compare with. Tests also need to be repeated several times to see if they form any pattern. Even things like ambient temperature for each test need to be considered, because that affects cooling of the pc, which definitely can affect performance.

Unless all these parameters are met then it's just a subjective view rather than a test.

I agree. I will continue to run objective tests. Believe me, I want to know the truth from my tests. I fly p3d EVERY DAY under all types of weather and various settings. I delete configs and delete shaders and do all the things recommended in this forum and elsewhere. The ONLY thing I’ve never done was deactivate FSUIPC...until yesterday.

Not using NCP to force 30 hz.  I’m using NCP to force 30 FPS. I’m running at 60 hz. 

Of course, 30Hz cannot be forced if the monitor is incapable of it.

It would be far better if questions on how FSUIPC might affect performance were posted on the correct forum.

However I do really need to correct some misunderstandings about what could be happening. 

Most of what FSUIPC is doing, most of the time, is passively receiving data from SimConnect.  Most of what is might do actively is in separate threads, not the main threads used by the sim as far as possible. These activities include device polling, depending of course on your assignments, and obtains data on AI aircraft newly added.

Activity in the main thread which may just possibly impinge upon performance is mainly that in responding to client application requests. 

So the only fair comparison regarding FSUIPC and no FSUIPC would be with no other programs running which use FSUIPC. (I notice, for example Radar Contact mentioned, quite a heavy user of FSUIPC that I remember, especially if you have any AI traffic).

I posted here, Pete, because there has been quite a bit of discussion regarding P3dv5 performance.  I also thought I'd reach quite a few more forum members here who otherwise might not be connecting performance with FSUIPC.  If UTLive obtains data from FSUIPC, then I guess it's possible that may be the reason I'm flying so smoothly.  I certainly can re-engage FSUIPC and disengage UTLive.  That would be a good experiment to confirm that.

UTL does not require or interface with FSUIPC. I am a UTL user and don't have FSUIPC installed.

How about the aircraft or (specifically) the panel? I was introduced to FSUIPC years ago because I needed a specific panel to work. Point is, there are a lot of moving parts and disabling FSUIPC may not just disable FSUIPC.

Cheers!
