Describe the Bug

With the new beta Capture method the host processing latency showing false numbers which are constantly increasing from the start of the sunshine executable reaching really huge numbers which for sure are not actual values as the performance is pretty good not getting such huge latenies.

Example debug log entry:

Debug: Frame processing latency (min/max/avg): 304.40ms/321.20ms/305.11ms

Expected Behavior

Show actual host latency values just like with the dekstop duplication API.

Somehow it is connected to boot time. On a freshly booted windows it has small values and constantly increasing to unreal numbers like 3700ms until next reboot.
