Hi,
I tested the new 8.2. M0 for some days now and it seems to works better, but not great.
For some reason,
8.2.Beta 2! worked perfect for me!
Beta 2 was very smooth and the difference I could see is - just one WUDFHost in the processes, which basically causes zero CPU usage (?).
However, 8.2 Beta 2 behaves completely different to any other beta/release before or after.
### EDIT ###
Sorry, after uninstalling and re-installing 8.2 Beta 2 I cannot reproduce the "great performance" mentioned above again.
