RPN Update Frequency

[MSFS 2024] Bug Reports Aircraft
, ,
1

Version: 1.4.20.0

Frequency: Consistently

Severity: Low

Bug description:

In MSFS 2020, the SDK documentation stated that the update frequency for the RPN Update Template is 1/frequency, capped by the framerate. In MSFS 2024, the frame rate does not cap the updates. As a result:

  • MSFS 2020: 500 @ 45fps = 45Hz update frequency.
  • MSFS 2024: 500 @ 45fps = 500Hz update frequency.

Was that an intentional change in behaviour?

Hello @MartynJF

Are you referring to this page?

Hi Sylvain,

I’ve checked with our developer and they said:

I was not referring to any particular preset, just the generic “ASOBO_GT_Update” template with any number for . Regardless of the actual method, I have code that’s running at the framerate speed in MSFS 2020, and at the 500+ Hz specified update speed in MSFS 2024, which breaks functionality.

Thanks,

Hello @MartynJF

According to our systems team, there are no reason for the updates to be limited to framerate frequency on 2020. I was always supposed to match the requested frequency as much as possible.
Optimizations in MSFS 2024 make it more likely, although there’s still a hard limitation, which is that an update cannot be evaluated more than 8 times per frame.
It means you shouldn’t be able to reach 500Hz at 45FPS.

Can you let me know which aircraft and what behavior component is impacted so I can have a look?

Regards,
Sylvain
