I add this game because it seems to have ATi Mach64/Rage 1/2/3 acceleration, but it accelerates in DOS or Win9x (DOS mode) only. Vesa mode works also in pure Win9x.
Airline Simulator 2 (Nomissoft) - 1999

This is not W9X game,has Acceleration
Designed for Mach64 line of ATi cards.

ATi cards need correct configuration files to Accelerate:

VESA compatible graphics can be used under Win95/Win98/WinME directly, too. Mach64 accelerator (used with ATI 3D card)
will run much faster, but is not compatible with Win95/98/ME mode - you can always use VESA mode with that card, too.
