Quote from: lmimmfn on Today at 04:07That's what I understood from Gunheds post: When you scroll the screen by one character, the CPU has to update that part of the screen, that is shifted out of one border and into the opposite border. Otherwise your screen would not scroll, but roll. With a character height of 8 lines, you have to update 8x 80bytes and with a character height of 2 lines, you have to update only 2x 80bytes.Quote from: GUNHED on Today at 02:54It only matters what the Z80 does. The less you shift the screen, the less RAM the Z80 needs to change. The CRTC does it's work independent, like all other chips too.That's my point really, Z80 has to update the screen and outside of the Z80 processing time the screen is updated via the CRTC.
Which brings me to the point that 2 pixel character screen setup has no advantage over 8 pixel characters Smooth vertical 1 pixel scrolling is completely independent of vertical char size or 1 byte horizontal scrolling.
