I gonna ask another similar question - about render options in this games. Which is the best?
GDI, OnepGL, DDrawCompact? (as far as i know the native mode for the original version of RA was GDI? - don't be confused with another GDI☻)
I suppose firts RA is complete remade (unlike Tib. sun and RA2 - in their case the original drawing process is used, but for compatibility reason -a wrapper is used , if i got it right)
