HI Jean-Luc.   Instead of again trying to reinstall the 750 from my previous download, I did a new download from your web site, installed that and now the 750 does seam to start okay.  However, I am now noticing a Big loss in performance when the 750 is on.  When it is off my FPS are around 35 FPS, but as soon as I turn on the 750 the FPS drop by 10 to about 25 FPS.   I have tried this several times with the same result and I have never experienced this before, either in XPlane or P3D.

Here are my RXP log files:

17/06/01 14:30:48.478 06472 -    ] # win.xpl version 2.4.0.0

17/06/01 14:30:52.968 06472 -    ] # rxpGtnSim64.dll version 2.4.0.0

Please let me know if I can provide any more information that would help you.

Thanks,   Howard

I don't know how you run the GTN on P3D because the P3D version is not available

Please make sure to try the latest version posted at the top of this forum. This should help a lot.

I think that is the version I am using.  It did help with the start up, but the frame rates still drop about 10 FPS when the 750 is running.

log file shows v2.4.0.0 whereas the latest is v2.4.6.0:

As for frame rate drop, can you cross check you have not set "DebugValue=" in the "RealityXP.GTN.ini" file located in your aircraft folder?

Sorry Jean-Luc,, but I cannot find  "DebugValue="  any where.
