Perhaps this is already commonly known, but despite the smaller mouse cursors and increased CPU load, there does appear to be at least one subjective merit - sprite scaling takes advantage of the increased, 640x480 resolution, meaning your character/monsters/etc. look less like Minecraft denizens at a distance.

Note that these screenshots were taken using the floppy-disk version of the game (in DOS). For reasons unknown, I get graphics corruption when attempting to use the same VESA driver with QG4CD in DOS, whereas the higher resolution can yet be had in Windows (notwithstanding the additional limitations imposed there...). But hey, since only the floppy version supports use of the Logitech Cyberman and its "force-feedback" gimmickry, that's really the only version worth playing anyhow, right?
