Suggestion for FPS

[vcaptain747 44]

Hi Nico,

This idea came while I was debugging my FPS issues. It's not a big deal, but it might be nice to have.

The idea is to add an option that allows the user to set an in-cockpit Target FPS. When injecting traffic, PSXT would monitor the current FPS reading from the sim and limit the injected traffic as soon as the FPS drops bellow the target threshold. 

I know that we have the parked % already, but we know also that the FPS depends on many changing factors such the user aircraft being used, the injected models complexity and the number of live aircrafts at a given moment. This might be useful especially when arriving to a busy airport and would relief pilots from playing around with the percentage chasing optimal FPS.

Thanks,

Amine.

PSXT cannot detect the user being in in-cockpit view...

Furthermore, an algorithm for such a target can be very tricky  with risks off oscillations, extra stutters because of aircraft swapping in and out,  and so on.

Not a good idea, imo. You as user have all the controls. But don't stop coming up with ideas, very much appreciated!

BTW. In the past I have tried to reduce the update frequency for aircraft further away from the user then 8 nm to once a second, but that did not help much, and then I also faced the problem how to detect the user being in the cockpit.

FSPS is working an a dynamic LOD tool where you can set a minimum lOD and maximum LOD depending on altitude.

Eg : on the ground LOD of just 50 and at 20000 + ft a LOD of 150-200

This will help with more FPS on the ground and when flying at lower altitudes.

Thanks for the feedback Nico.

I beg to differ 🙂 . The CAMERA STATE simvar gives you that information when requested for the user aircraft . if it reads 2 then cockpit camera is selected. The real issue though is that there is no simvar for FPS . I wrongly assumed that the SIM RATE simvar was for FPS, but in reality it refers to time acceleration within the sim .. so that's a dead end.

EDIT: turns out the CAMERA STATE was newly introduced in MSFS SDK and did not exist in FSX/P3D SDK.

I agree. For what it's worth, I thought of it as a way to calculate a dynamic parked% based on FPS during the initial load and then PSXT would use it as it would use the static one from the airport file.. but I agree that FPS also depends of many other factors that could cause it to go wild and end up impacting PSXT performance.

I won't 🙂  . As a matter of fact, I recently started to explore the world of simconnect and the more I read, the more questions pop to my head, some out of curiosity and some could turn into suggestions for improvement. If you don't mind the curiosity of a simmconnect newbie , then I'll be happy to share them with you for sure.

Thanks!

Amine.

Thanks for bringing that up.. it sure will help with FPS.  I used to have FFTF dynamic P3D from FSPS and it was useful to some extent.
