For QuickSync, I have enabled it from the Bios and went into the Screen Resolution in Windows to connect to the fake display and extend to it. Afterwards, I have rebooted my computer.

Testing environment -- Using the Payday 2 Main Menu Screen Running in Windowed Mode and using Borderless Gaming to make it full screen
Measurement -- EVGA OC Scanner X

Looking at the GPU workload --
Game Capture --
Not Streaming -- 54%
x264 -- 64%
QuickSync -- 64%
NVENC -- 67%

Window Capture
Not Streaming -- 54%
x264 -- 70%
QuickSync -- Jumps from 60-70%
NVENC -- 74%

The jumps in GPU workload is noticeable by ingame FPS.

I noticed that I can include a log file. How do I clear the existing log file to start a new session?

Thanks!
