Windows 10

[FinalBlast]

I haven't had any of those issues, it could be driver related for you, I
have disabled windows defender, so far unable to disable cortana anymore,
she keeps coming back, otherwise all emulation is actually even better
than it was before, on laptop there's a biiit more heating problem
(only on w10, on w7 its fine), but all applications went +20 fps for me,
so a cooling pad fixes it, on my desktop its way better than w8.1.

One of the features I really like, are the Game DVR(video+audio recorder)
works on any window except for the desktop itself, game or browser/program,
works fine, not too big in size (.mp4) and its a lot better than fraps,
not exactly like Shadowplay, but close..finally something proper
to record with on my laptop with an AMD gpu! =)
