Ok thanks for that info. 6fps is certainly a little too low

. 17 is not too bad though - although not great - I may get more as I will not be using a VC, simply external views...
Looking at a couple of the commercial aircraft available (the Wilco 'Buses for example), it is possible to make "detachable" vector gauges to view on a separate monitor using GDI+.
From a purely practical point of view, how many monitors can be run from one PC? Using, for example, 2 very high end (1GB) dual head NVidia or ATI cards on a super high spec PC (quad core, 8GB RAM, Win XP x64 or Vista x64), would it be possible to run 4 monitors? And furthermore, would FSX support the use of this many monitors at one time?
I am thinking that even though one ultra high spec machine would be very expensive, it would still be cheaper (especially once you take into account multiple licenses for FSX and all the addons) than 2+ high spec machines...
2 more questions (sorry!):
1 - can external views form part of a gauge (you might be able to see where I am going with this... The A380)?
2 - Would it theoretically be possible to read airport data from an AFCAD or other file and "draw" a plan (looking down) schematic of the airport and your aircraft's current location in a gauge or external application (either on the same system or on a networked PC)?
I have tried to condense all my graphics related questions into a single post, so apologies for the lack of brevity!
Many thanks,
Martin
