Thanks for the info, yes probably be fine, I detune my FSX similarly to you but as I do a lot of water flying or uninhabited areas it does not matter that much. I run the Captain Sim jets without any problems (except like everybody else in FSX, full blown bad weather into a large city somewhere always gives it the jitters, so this beastie should not be a problem my system is 64 bit. It will have to wait for a bit, too many other things on the run at the moment.
I am surprised that the rush to do paints and screenies seems a bit slow, guess there is a lot of learning to do for some folks.
its because there is no FSX/P3D paintkit and there are some differences between the xplane and P3D version

And since the DC-6 i'm virtually dead and gone to virtual heaven. Never thought i'd see that virtual day ! 
) so i only use the freeware FSUIPC version on 'auto bases' (some models seem to need it).
Equal passion i'd say
