Yes, you have to install the Logitech software to get the high resolution mode - or you have to use a Linux where this is compiled in the kernel. Maybe someone can port this stuff to Windows.

In the meantime I've just checked with Spy++ that my Logitech M705 sends in high resolution mode WM_MOUSEWHEEL-messages with a delta value of 1 when I scroll slowly (which means it sends 120 messages instead of 1 at normal resolution for the same angle) and if I scroll faster the delta value grows up - I think the driver accumulates the delta to avoid a message overrun.

That results in the strange fact that I can adjust the volume level better when I scroll faster because it generates less messages.

When you google "Improve Zooming with Enhanced Mouse Wheels" than you find a page with a HiResScrollWheelEmulator for emulating a mouse wheel with high resolution. Of course you have to trust the application on this page for using it.

Just a little update - I installed Logitech options software and with my M720 was able to reproduce this (my Logitech G9 does not appear to have such options - maybe because it needs setpoint rather than "Options" which AFAIK is not available for Windows 10.

Anyway, I have modified XMBC to respect the highresolution scroll - seems to be working. It will be available in the next release (whenever that may be).
