BlueTooth Audio and Game Controller support unreliable on 13.1RC1

Bluetooth is a huge issue in Ventura that has not been fixed in 13.1 RC1. If you have more than two BlueTooth devices connected, sound to even AirPods goes to hell with crackling and interruptions. Game Controllers also lag. This is on a high-end Mac Studio. I have left "Feedback" and am really ticked off that this has not been addressed. This used to work just fine in older versions. BTW, the PowerBook M1 13" also had these issues when it was first released. The unsatisfactory solution is to connect Magic Keypad and Trackpad with Lightning USB and turn off the mouse. Has anybody else run into this? There are a lot of reports on other forums. I have deleted all devices and reinstalled them to no avail. Does anybody else have this problem or a solution?
