From what I've read here, 1000Hz is causing issues (at least on real-time kernel) from time to time, so going with 300Hz is safer. For short period of time there was low latency kernel (RT) and it was running very good but for some reason it was converted back to 300 Hz. There is only one way in this situation which means, do it by your self and I doubt that will change sooner or later, so asking for it is pretty much waste of time imo.
Maybe my memory is failing me but every time when low latency kernel topic pop up there is only one type of answers for it. Good idea make it by yourself, here're links. Thank you, goodbye. Ok, maybe two, but second is 300 Hz is performing better (but this applies to RT).
So this can be part of issue here I guess (low demand for that).
