I had Bidirectional DSHOT and RPM filtering enabled, but I still couldn't get rid of some oscilations on my quad (Diatone Roma F5, 6S, Caddx Vista).
I went through this article and I gave it a try, changing DMA settings:


After that, the qwad at the frst arming went crazy   


So, I reverted dshot_burst and scheduler_optimize_rate back to defaults and arming went perfectly. But when I add a bit of throttle, motors gets jerky    (as you can hear on this video - sounds kinda like a loose propeller, but it's not)


Is it possible that the above commands could destroy my FC, ESC (perhaps motor/s) ?
How do I investigate this further?

Kindly, Artur.

Mystery solved. 
scheduler_optimize_rate setting seem to be messing up Bidirectional DSHOT settings itself. 
It should be set to AUTO, otherwise Bidirectional DSHOT won't work.

Thanks for the update
