[S5E4] Unchained

DOOM had a low-res mode (toggled via F5) that doubled the width of the pixels being plotted by messing with the write mask in unchained VGA mode. That, coupled with the triple-buffering used, made the game majorly fast and quite playable on a 386/40. Carmack was experimenting with a Hi-Color mode that allowed more than 256 colors on the screen, but that mode halved resolution. He wanted to see what it would look like because it got rid of the color-banding due to the diminished lighting, but 160-pixels horizontally looked very bad so they removed it. Up to version 1.1, it was possible to run the game on three monitors at once, giving a 270-degree field of vision.
