OBS is great - I use it for recording videos here at PG Music, as do some of my colleagues.

I did find that it does not work so well in Windows 11 while I was recording the demo video - quite a few times OBS stopped all audio from working, and there were a couple times where the screen recording froze but the audio kept recording, so I often had to repeat what I just did. Screen recording can be a tricky thing though, as it usually has to try and hook data from the graphics driver, which in Win 11 might operate differently than Win 10. Indeed I had a fair bit of difficulty with some things in this very early release of Windows 11, although Band-in-a-Box and RealBand both worked great.

Rambling aside, OBS is great software which I'm sure will work great with Windows 11 once the OS is out of beta.
