I have been testing FSX SE for couple of hours now and can report that Dovetail have altered some things with the coding. I was able to use DX10 for the first time ever, with all sliders up and frames locked at 30fps, I was getting consistant 29.9 - 30 frames in the stormy weather scenario( overcast ). Smooth running with no stutters. I think we all know that Dovetail will be on the addon bandwagon same as train sim, but whatever they have done with FSX is good indeed. Cant wait to get the PMDG birds in there.
