2004 needs more CPU to enjoy all the eye candy. Having said that it is much
better than 2002, first of all with ATC. Better vectors to avoid mountains
and choice of runway on arrival. Better online weather and 3d clouds. The
patch has fixed some cosmetics like putting bridges back, but also corrected
some memory leak problems with autogen.
I wasnt too crazy about 2004 on my P4/1.9 rig but since I had to get a new
PC with a P4/3.4 2004 is a real treat and pleasure to fly. 2002 is now on
Really depends on your present system.
