Tested with latest nVidia beta 6.11 drivers and latest Realtek drivers which came out yesterday or the day before.
Audio transfer speed (hardware). I assume higher is better?
What's the difference between having more hardware buffers?
Realtek's drivers consume 6% CPU time consistantly and nVidia's 8% consistantly. There are very minature dips and rises less than 0.01% CPU time on the graph.
So my CPU usage is nearly a mathematical exact 6%/8% respectively meaning there are virtually no performance fluctuations.
If one has less audio transfer speed but more hardware buffers does it make it better?
