[vfio-users] BSOD occuring with 1 game in VM

Thu May 12 19:52:14 UTC 2016

Same, does not work, even with the multiples binaries of the game (launched
threw battle.net)

Just for people to know it makes the card have this kind of herratic gpu
usage during game... Which is quite a pain to play...

Note that it became more quiet while entering menus after game end (after
the line with the hour...)
