1) did you test it with Windows Vista (beta version)?
No ... Windows XP
2) which graphic card are you using? and what framerates are you getting during flying and during taxing on ground?
I'm using my quad system ... the drivers are very new and not the best for frame rates ... :(
I'm getting around 20fps at 3840x1024 everything in high and AA is turned on. It has settings for very high but if I try to use it the game junks out to desktop. It runs better on the normal SLI system (2 x 512Mb 7900GTX ) so I think it is the Quad drivers ... but even then I think it could do with some more fps.
3) did you use three dell 2405 to produce the 3840 x 1024 screenshot which is at the very bottom??
I used 3 x Dell 2001FP (3 x 20" 4:3) for all the TripleHead shots (not the 2405's as in my sig/system specs)
4) I do use the 2D cockpit view a lot now for FS9 and plan to use it in FSX. From your screenshots, the cockpit view is strectched and the looks of the gauges is not acceptable to me. Any way to correct this (to produce a normal looking flight panel just like what you see in a single 19" LCD mon)?
Not that I could find ... :(
I would say that it is only just playable in TripleHead because of the zoom feature and so if I were you I would try to get to see it somewhere if you are going to spend out on TripleHead just for this game.
Hopefully the framerates will improve with newer drivers and DX10/Vista
