About sound guys. It's bad :/ Well, I have 3 detected devices,
1. on nvidia
2. integrated on mb
3. wireless usb dongle
With usb ALSA fails that it has not enough data in stream, I decided that it is hardware caching problem and just use integrated while play, all others are disabled. However it still lose sound, mostly when I do alt+tab while loading. Quick fix is alt+tab to anything, connect/disconnect dongle and sounds back on embedded.
Have no idea why
I'm 3rd week on Linux only.
About graphics - I was using on Windows low-medium, so having same on Linux is enough for me
Also I have steady sound lost doing Void Star + lags during and after that. So now I just leave this WZ immediatlly, i suspect same bug/leak as with map markers.
