Some kind of lightweight lossless or perceptually lossless codec is ideal here. There's software that can do this, ideally leveraging the CPU's HW encoder so as not to burn a lot of CPU during that game. That said, a lot of those encoders are subsampled by default so some tweaking might be needed. I've not done screen recording for ages, so I'm not up on what today's state of the art is.

Alternatively you can capture HDMI out if you have that available. The cheap HDMI capture solutions are 4:2:0, though.

I don't know what can capture to >8-bit on-PC. An interesting comparison would be between 10-bit 4:2:0 and 8-bit 4:4:4, when those are availble. Some devices, like Xbox One X, can even render and output 12-bit over HDMI.

i mean we can talk a lot but test are the real thing.
Huzzah!

And heck, I see I have some 1080p60 RGBA recorded game clips on my RAID. I'll try to whip out some quick tests.

Any preferences between:
  1. CSGO
  2. DOTA 2
  3. GTA V
  4. Hearthstone
  5. Minecraft
  6. Rust
  7. Starcraft 2
  8. Witcher 3

There are captures from over four years ago, so they won't have all the latest bright and shiny effects.
