FSUIPC Data Rate

[mattford2]

Hi Guys-

Does anyone know what the maximum data rate that is available from FSUIPC? I'm writing a host driver to drive a brand new Level D Image Generator that was donated to my sim but am finding that the lat/long info is too slow to make the IG move smoothly.

Thanks,

Matt

FS frame rate is the base rate for most things like that, the same rate as FS uses for its visual updates. Lack of smoothness is not usually due to a slow data rate but an unsynchronized one. You need to throttle FS's frame rate to a value it is always going to achieve, so it stays fixed, and then read at that exact same rate.

The only other way is to use a fixed rate independently of FS and interpolate between for a faster rate locally.
