Just try on my rig: i7 5930k (6 cores 12 threads) 3.5GHz and GTX980Ti (so no hardware decoding of HEVC)

1080p HEVC: CPU usage around 10-12%

4K 10bits HEVC: CPU usage around 20-25%

In both cases, all the 12 threads of the CPU seem to be used even if I use an old Krypton nightly build from April 1st
