HI

there are two theories
1) its never enough we alway need more, more, more.  I have 400 Mb and it stills clocks a 1 frame per second when I'm on the ground. But maybe thats the processor not the memory.

2) if the box says minimum 64 Mb then it must be enough surely?  But then what OS are you using, Xp, ME, 2000, 98 - they all demand different levels of free memory, and the more you stick in the more the OS will hog for itself.

One thing is for sure are computers will never keep up with these demanding applications.

Happy simming

Phil
