PAL hires interlaced (640 x 512) should lok the same ona a VGA monitor in DblPAL mode. I think it is one of the most ingenious resolutions ever created by Commodore. Because it doesn do the stupid 640 x 480 of PC computers thus making the image looked Squashed or stretched.
Its not slow in my experience as some say. I use 64 colors witha 68030 and it seems the same to me.
except of course I use DblNTSC because I am in USA and use NTSC.
