I've been playing on Linux Xubuntu 16.04 in PlayOnLinux for a month or two now, stable fps, no tearing, same latency as windows, minor visual issues with settings side panel and non-latin letters. If you check my latest scores, given my skill level, it is the same as my pre-linux scores. So, with that as a metric, you could say it is the same exact experience.
How I got it running is simple:
- Make a new PoL drive (x32), with wine 2.0-rc3-staging (x32).
- Configure->Miscellaneous->Open a shell
- Enter the following (one at a time) :
Install newest winetricks:
wget https://raw.githubusercontent.com/Winetricks/winetricks/master/src/winetricks
chmod +x winetricks
Install vcrun2015
sh winetricks vcrun2015
- Go to the "Install components" tab, install dotnet40
- Miscellaneous tab once again, "Run a .exe file in this virtual drive"
- Run your osu! installer
- Play the game
Hope it works for you too, didn't post up until now to test functionality.
