Hi! Tinkering with the EXEHDR utility, one can find out, that the PlayMetaFile() is not a function of the display driver (which it should be, because from the question I realized that it would make sense). However, the display driver is what you'll replace along with the more intelligent display unit. It seems, that the net gain would be limited to letting the new graphics processor do the line/circle et al. calculations.
