Oof. The gamma on that screenshot.

If you want to see what it's supposed to look like, copy the screenshot into GIMP, go into "Color, Levels" and in the "Input Levels" section, there should be a textbox+spinner with a "1.00". Set that to 0.45.

Apparently Voodoo cards defaulted to 1.3 gamma instead of the standard 2.2. I wonder why that is, since it theory using a non-standard gamma would just reduce your color range with no real benefit.

This is definitely fixable in the design though by looking at the DAC gamma register. I'll do so once I get to the scan-out implementation on the DE-10 Nano.

I recall Quake orignally being super dark, Like you were supposed to be playing this in some basement tomb. But we were 'testing' Pentium Pro workstations in a brightly lit windowed office, so we had to adjust the game's brightness. So I wonder if this was a "make Quake look good for demos" thing.
