EDIT: 2013-11-10 - Solution: install old NVIDIA drivers.
As the title says, after upgrading from XP to 8, I'm disappointed.
Can't play use latencies below 7ms with RME Babyface, getting occasional crackles, especially when resizing time selection for an example - the higher red periods in the graph.
With win xp, with the same computer I could use 4ms easily, with 128 buffer size.
And the latency checker was in the lower quarter of green.
Any advice from more experienced Win 8 users?
