Performance issues with high-polling rate mice

This article is applicable to the following wrappers:
• slc’s Wineskin for macOS 10.14 Mojave and earlier
• Technocoder’s Wineskin with macOS Catalina 10.15 support
• Technocoder’s unofficial Wineskin for macOS 10.14 Mojave and earlier

Behaviour

Users may encounter issues when using high-polling rate computer mice with osu!, due to incompatibilities between higher polling rates with macOS and Wine. This includes increased lags and instability when using mice above 500Hz.

Cause

Mouse polling rates are a known issue with Wine., and although it has been marked as CLOSED NOTOURBUG on the WineHQ Bugzilla page, users have been experiencing issues with high polling rates and Wine. macOS has also been known to suffer from incompatibilities with high polling rates, including CPU spikes and game incompatibilities.

Resolution

There is no known fix for this issue, but there are different steps which have worked for different users.

  • Update osu!

  • Update macOS

  • Decrease polling rate from 1000Hz to 500Hz

  • Switch from a USB3 to USB2 port

  • Avoid the macOS Mojave 10.14.6 Security Update (user-suggested, unconfirmed)

User reports
