Mouse movement is somewhat jerky on my MOS Powerup installation no matter what mouse I try (different PC-mice using Cocolino, old Amiga mouse w/o Cocolino etc.).

Using the same setup and refresh rate in AmigaOS 3.9, mouse movements are very smooth.

Is mouse polling not synched to display refresh in MOS or what are the reasons?
Is there any way/tool to change the mouse polling interval (e.g. from 40hz to 200hz) in MOS? I only found a tool for Amithlon (ps2rate), but unfortunately it doesn't work in MOS.
