MiG29A not playing well with Pimax Play

[gwizairshows]

This mod has great potential.  Unfortunately it has some constant crash issues with Pimax Play resulting in game crashing to desk top. I have researched and tried numerous ways to comply with the online system crash advice, but nothing seems to work. Trying the old open XR and Pimax play start options initially start off fine, but then almost at the exact same spot taxiing from a cold start the sim crashes. It is very frustrating, especially considering the amount of time I have dedicated to learning this module. As far as my rig, I am operating a Cyber Power   Intel(R) Core(TM) i9-14900K, 3200 Mhz, 24 Core(s), 32 Logical Processor(s), with Nvidia GeForce RTX 4090.  So handling this module and DCS should be no problem.  These crashes only happen with this MiG-29A module.  It appears something is wrong with this module and Pimax Play.

Anyone else having these issues?

For me, everything is running fine with the OG Crystal. No crashes and very good performance. You might want to check if you run some unofficial mods or did do some fancy stuff to the finicky pimax software. A full repair of DCS might also help.

You may try to change order of OpenXR layers.

Can you please attach your DCS log file for when this occurs again. The log file will get overwritten each time you start DCS so make sure to grab it first.

Well... I just may have solved the problem.  I went back to Open Composite, activated it and disabled Steam VR in the Open Composite option.  Activated Open XR and Tool kit programs.  Started Pimax Play, and in the Games section disabled in the menus any reference to Steam VR (including aspects regarding the DCS Game Start option) and hit Apply.  Then activated DCS from the Pimax Game option (with all the Steam VR stuff off).  

Held my breath, and to my amazement flew a complete 40 min solo Nav mission out of Maykop from cold start to shut down.  Everything worked perfectly!!

Therefore, I am assuming the problem is actually with Pimax, (not playing with) Steam VR and something to do with those two that relates to the Mig-29A module.  Of course that was only one flight.  Will try multiple flights soon and report if all is okay using the above process.  Again this whole problem only seems to be a factor with 29A module, all others are fine. 

As I am fixated on the 29A for the time being, guess this will be the new DCS start norm using the Crystal for me.

Any reason why you're using OpenComposite? DCS is a native OpenXR game so shouldn't be used with that. And yes, Pimax should ideally be used with either the PimaxPlay OpenXR runtime or Mbucchia's Pimax runtime and not SteamVR.
