Pritchard's map video
I've recorded this one in 4:3 720p, to see if the performance would be better than 16:9 720p, but there wasn't any noticeable diference.
16:9 480p has almost the same image quality, but is much smoother. I'll go back to recording at 480p in the next videos.
Your settings are very dark! and missing all the colored lighting is seems?
Are you using the retroquad engine for this?
Yes. Retroquad doesn't have colored lighting.
The darkness definitely wouldn't help in the underwater (and darkest) section. It was never supposed to be played this dark - perhaps sneak your brightness up a bit so it matches quakespasm at mid brightness?
The darkness level is correct, and the brightness in the video is already twice the normal Quake values.
For some reason, hardware-rendered Quake engines are "washed out" when it comes to darkness. Shadows in them doesn't darken the colors as much as the original software renderer does, and you can confirm this by using the software-rendered version of Mark V.
Here are some lossless screenshots for comparison:
Retroquad, 200% brightness, as in the video
Retroquad, 100% brightness
It's a common issue that many people aren't aware of, because most people don't even actually remember what the original software renderer actually looks like, and almost no one bothers to investigate subtle differences like this.
Also, YouTube re-encoding and compression sucks. When colors get blurred, the brighter colors gets darker because they're mixed with the darker colors. When actually playing the game, the darkest spots aren't that dark.
Maybe in the future I may try to replicate the brightness curve of the lighting of the hardware-accelerated engines, and add it as an option.
