Yeah, seems to work pretty well on my Steam Deck. It's probably using more power, but it's a small enough increase that I couldn't confirm increased power draw without exporting mangohud values and averaging them.

I dropped the recorded length to 30min (mainly just want time to grab a noteworthy clip if something funny happens).

Yes. It's very convenient.

But it needs more config options.

You can't set a recording resolution, it seems to max out at 1080p. On my 3440x1440p ultrawide I get 1920x804 as it fits the ultrawide aspect ratio into the horizontal resolution of 1080p.

It only uses h264, new cards support AV1 so would be nice to actually use that.

Yeah, it works well and haven't noticed any type of performance impact.

It seems lacking in features on Linux. I figured out how to record (always on in background), but the other tools either don't seem to work or aren't documented. e.g. reviewing clips, any sort of interface, the shortcut keys didn't work for me, etc.

I need to set it up when I'm back at my PC, and just let it eat, I'm down to give it like 500gb and see how much it keeps

I use NVIDIA shadowplay for that.

I have, it's pretty good so far. The editor needs expanded tools, but otherwise it's a damn good beta

No, didn't know about this. My graphics card software has a similar feature that I suspect is slightly better for performance and works on everything, not just steam games.

I wish it was working for added Non-Steam games too

When I tried recording a Non-Steam game it just didn't record anything

Not yet, I'll wait for it to hit the stable channel

I don't know if it's a problem with my OS but i couldn't select audio sources. The button was grayed out and set to "all system audio" so I didn't use it as the quality of clips was worse than GPU Screen Recorder. I just want to watch stuff on the side while playing games without that audio getting recorded but i heard doing it through OBS has a bigger impact on performance.
