After using the PMDG 737 NGX for many months and enjoying it greatly.  Today I entered FSX and at UK2000 Gatwick loading the NGX my framerate went down to 1.5.

 

I tried default aircraft eyc and different locations and was getting 30+ FPS.

 

Nothing in m y PC has changed.

 

pls can you help

ALL PMDG files are up to date

Is you're speech recognizer set to English - US?  Double check it.

 

From FS2Crew's vantage point, that's the only thing that can totally trash your frame rates like that.
