PMDG 777 with ReverbG2 and WMR....memory leak ?

[joby33y 154]

I am noticing a major lag in graphics response after switching in & out of VR with this airplane.  Switch in to VR and it works fine.  However, switch back out to 2D, the frames are lagging and looking around the cockpit is slow and sticky like slow motion.  

This is a brand new corei9 / 4070 setup and all other airplanes work fine, including the Fenix A320, PMDG 738 and Horzn 789.  I hadn't seen this behavior until flying the 773 over the last couple of days.  Feels like a memory leak or something.   Once I kill the WMR process, all is reverted back to normal.  

Ideas ?  anyone else noticing this ?
