FlyPT Mover

I noticed a weird problem, happening in 3 games (ATS, ETS2, Dirt Rally 2.0): when there is a sudden and large movement of the rig (i.e. going on the high curb or anything resulting in a significant and fast roll) - it often suddenly freezes the game and drops the framerate to a slideshow, braking VR so badly that both eyes desynchronize and it's unplayable. Getting out of VR and back in usually fixes it for a while, until the next curb. It's 100% repeatable and always happens on big rig movements.

I'm puzzled as to how it can be connected at all. I suspect FlyPT may do something to the CPU, because closing all its windows cured it for me once, though the next day it happened again even with all windows closed. It never happened in MSFS , but driving sims are new to me, though it didn't seem to happen initially, and just started to happen recently. I am constantly adjusting presets, but there's nothin over the top there, and my rig is just a 2DOF. I'm not sure what's the reason and how can I overcome this.

Obviously, the result is a crash and a vomit-inducing VR desync, so I'd better fix it.

My hardware is pretty much top-of-the-line, so plenty of CPU to go around. RTX4090 + 7950X3D + 64Gb fast DDR5 RAM. I do use Process Lasso's CPU Sets to force FlyPT to use CCD1 (cores 8-16) and force games to CCD0 (cores 0-7) with X3D cache. But with 16 cores /32 threads there are plenty of cores for FlyPT to work with, so I doubt that's the problem. I'm on Meta Quest 3 + Virtual Desktop via a WiFi6 router. "Use high precision" is unchecked.

Any ideas?

i know this bug. do you use OXRMC? if so, it is correction on rotational axis. if you put 0 (zero) as a value in virtual tracker on all 3 rotational exis instead of "value" then it's gone...

it is related to meta/quest3 only. the developer behind oxrmc is already working on it but it has nothing to do with mover other than it is caused by roll/pitch/yaw on virtual tracker causing it. of course if you put ZEROs there it will mean there will not be compensation on those axis... i spent enormous time to track the issue together with other guys on discord. in MSFS it happens ie. when you land hard... you can enable pitch and then if you change pitch slowly it will work - it looks like IMU data doesn't correlate with what VT sends and it breaks if the change is sudden...

Is it possible to have a filter that detect when the value is negative and apply a lower output gain on it or something similar to make the movement less hard on one side.
This is on my pitch (the one mixed with surge). It feel a little too hard when braking but is ok when accelerating.

YES!!! Wow, thanks, you saved me lots of time trying to figure it out. I'll look up OXRMC Discord to see when it's solved...

I don't have the solution, but I agree with the premise - in every game if I increase the surge-to-pitch mix until acceleration feels good, the braking feels brutally hard. So I settle to having braking just a little too much, and the acceleration is barely noticeable. There should be a way...

It will be on next release:

Example:

...Still on it
to keep you interested, a new filter:

Interpolation to increase some games data resolution

Wow! This software can be used for industrial purposes as well! I can't wait to have it on hand.

You might be interested in CRC check for that:


or the new output string features:

Incredible, we are way beyond expectations here! This software can be suitable for all servo systems!

About MODBUS, have you found a solution for the congenital Windows latency on the serial port? Of course latency doesn't matter for CNCs

Honestlly, did not look into latency for serial. Code is new and interpreter way faster than it was.
It's on the list to do a specific serial library, but it's not for now.

hello atous is there any chance that fly will be updated on the latest licenses like LMU, WRC, F1 23 thank you

This software is on an unbeliveable level. We are a lucky community indeed.

I've been having this issue with my wind arduino, thought i could tackle it today.

When i hit disconnect, it gets stuck on 'Stopping' and freezes Mover until i physically pull the usb cable from it:



I'm thinking i need to add something in the Stop String, but not sure what. Possibly "STOP"?. And, what to put into the arduino sketch to do what is necessary after reading those characters. If i do a serial.end will it be able to start up again? even without serial i have a knob for manual wind control, so code is still running.

arduino sketch here: https://pastebin.com/7gm42M1Y

edit : SOLVED
// get disconnect "STOP"
if (bytesBuffer[0] == 83 && bytesBuffer[1] == 84 && bytesBuffer[2] == 79 && bytesBuffer[3] == 80 )
{
Serial.end();
setup();
}

I have had this issue if I have set the COM port to the incorrect number/device. Are you sure 6 is correct? Have you any other COM port modules set in Flypt that could be incorrect?

yep, i just edited my post with the solution.. needed some code to stop serial

Hey guys,
Wondering if anyone uses a vive tracker with OpenXR motion compensation?

I cannot get it working even after editing the .ini and selecting (vive) as the tracker source and saving the config file. When I select (flypt) it works fine, but I'm trying to use a physical tracker (Vive 3.0) on my rig (6DOF). The tracker is setup in SteamVR and it is registered in the Varjo Base app as well.

I'm using the Aero with OpenXR.

Any help is appreciated.

Please excuse if this is the wrong place: I'm looking for a profil for FlyPT for MSFS2020 and the Cabri G2 which is as realistic as possible. Is there a place where I can find something like this or does someone have a profile to share ?
Thanks in advance
Michael

Hi was wondering if there is a flyPT plugin/settings when using it with Simtools Ride player? Tried different Source within the FlyFT app - 'simtools' and 'Custom UDP' but so far FlyPT Mover is not connecting to Simtools.

How do I select FlyPT_Mover interface type when I have FlyPT app running? see attached image

I originally added this question to the FlyPT thread but admin moved it to New users.
Many thanks
