I often wondered why Doom on my 060 and CV64 flew in full screen, but AB3D2 was slow, as was Breathless( i think this has soemthing to do with the 060) and Gloom even rtg Gloom. The Glom vs Doom thing makes me think that C2p routines arent as well optomized in Gloom as in rtg Doom as they both use the same hardware. I thought that Nemac IV had the best and fastes graphics though.
