The white and red Piper J3 Cub is on my Pentium i3 computer with 4 processors and a 1MB graphic card. The yellow Piper J3 Cub is on my Pentium i7 computer with 12 processors and a 16MB graphic card.
The final screenshots are above the airfield. The display is very similar on both computers and the aircraft handle equally well.
The main difference is that with the older processor, boot up takes about 12 minutes, whilst the newer computer will boot up the program in 2 minutes.
