Quite so! I'm sure I could have fiddled with ffmpeg commands, set up a custom Steam launcher, etc. I probably would have if OBS Studio's preview performance introduced too much overhead.
I also discovered that OBS Studio can be installed directly from the Steam store, which makes makes the whole thing feel just a little more seamless (I'm streaming to the Steam Frame). I don't mind trading the extra install space for that feeling, especially since OBS is OSS. It was really pleasant to have this all "just work" end-to-end on both Linux and Windows stacks.
