Windows 10 does allow game capture, along with any microphone chatter if permitted.

But i think the reviews were that it's good for quick captures and uploading to share with friends.
The quality is decent for most.

I think with the biggest appeal would be for youtubers/twitchers for fast experiences.
There's little control over quality besides some presets.
I don't think they have a lossless option for editing.
Screenshots can be lossless I think.

From experience, playing games like Subnautica have options in-game to "dither" the image which reduces banding and "lense dirt" to help aid in reducing banding.
But, their dither is just a single pattern and shows up badly on other textures that aren't the skies or distance waters.
Lense dirt (or more like lense flare) is pretty decent.
For capturing gameplay like that, I'd rather not enable the in-game dither and just deband it later in avs.
The banding can get extreme in Subnautica.

Using Windows 10 DVR is something I'll look at to benchmark all these options.
