Right, the native drivers won’t store your settings which is super annoying. Also, I had a really hard time adjusting the resolution and other settings in obs. It would just turn the output black most of time.
If you use the Logitech drivers, you can control multiple by exploiting the “chain of command” Jack danger talks about it in the tilt forums streaming thread. Garrett Hays also has a write up on tilt forums as well. It’s a pain in the ass, and involves unplugging the cameras in a specific order. But it works. I’ve ran 21 c920s at one time using this method.
