[Problems driving MS FS2004 Position using FSUIPC]

What do you exactly mean with "choppy" ? We get smooth flying - very nice!

Try installing FS9 on two separate machines. On one machine read FS UNITS and send them continously over the net without conversion. On the other side put directly the FS UNITS in FS9 and see what happens.

That's a good idea, and probably answers one of my questions. We use WideFS for our network transport, and it sounds like you use your own ethernet routines. Does your ethernet run under a real-time system, or are you using Windows timing functions?

Straight and level flying looks fine. It's takeoffs and turns that don't look smooth. There is subtle lurching on takeoff, as if it misses a frame then jumps ahead two. Turning is similar - the heading doesn't change as smooth as it should.

My suspects are either my scheduler (trying to make Windows XP act realtime is a mess) or the network transport (maybe WideFS is queing up two passes, or some such thing). I'm writing an app to do a takeoff with canned data, so it can run on the MSFS PC, which should eliminate network problems. Running flight siim data to flight sim would help eliminate the network. Then, I'll be stuck without ideas again...

[Problems driving MS FS2004 Position using FSUIPC]

When driving aircraft position via FSUIPC you have to:

- set SLEW MODE or

- set PAUSE MODE or

- set SIMULATION RATE to 0 (but this prevents you from seeing effects like rain, moving AI aircrafts etc).

BYE!

A few other things:

- Limit the rate of MS Flight Sim, and try to match the rate (or maybe beat it slightly)

- Set HIDEINFOTEXT=1 in FS9.CFG (see http://forums.simflight.com/viewtopic.php?t=35693)

However, you may not be happy with the results. I've done all of this, running over the network, etc., but it still looks choppy. Not horribly choppy, but not as smooth as MSFS flys or slews.

Has anyone gotten really good results in dynamically updating position using FSUIPC?

[Flashing Slew Indicator]

Thanks - that worked for me, after I found FS9.CFG. The file Readme.rtf says where the file is:

• 
  [*:f0ec7] Windows 2000, XP : C:\Documents and Settings\\Application Data\Microsoft\FS9\
  [*:f0ec7] Windows 9x and ME: \WINDOWS\Application Data\Microsoft\FS9

[Flashing Slew Indicator]

I'm trying to drive MS Flight Sim '04 with FSUIPC, to use it as a visual for a simulation with its own flight model. I've been using Slew mode, and after matching the rate closely, it looks fairly good in full screen mode. However, I have this red flashing "SLEW" indicator in the lower right corner. Is there any way to get rid of it?
