I intially had problems(CTD) with the latest hotfix so I went back to the previous fix which worked fine then i was getting panel freezes in VC. So decided to try the lateset hotfix again. And low and behold no problems....weird.

I am sense (all subjective of course) a smoother "NGX experience" and believe there is a slight fps gain judging by the fps numbers (I usually never have this displayed while flying). Landings are refined. The NGX is exceptional in so many ways and runs without a hitch.

Sorry to say the HF4 after loading (about 30sec) games crashes for me :-( Have done a system restore and all is well again. Thinking about the saying..."If it aint broke don't try and fix it." Other than that 1 truly happy PMDG x 2 customer here. Sorry I can't give any tech info to help. Paul Humphries
