The default mouse settings are always too slow for my liking; I always speed up the tracking speed. I haven't used a Magic Mouse on a regular basis for a while (had both the v1 and v2), but once I updated the setting, it was as snappy as I wanted.
I already set tracking speed to highest but this is really one of the worst mouse i have ever used. Only reason i am still using it my other bluetooth mouse is seriously laggy when i use with m1 mac.
