I have my custom presets for rendering videos for YouTube and "Fast video rendering" (Hardware video encoder) was always available. Today, during rendering process I had to restart my PC and after rebooting this option is no longer available.
It is available for lower resolutions like 1080p and lower but no more for 4K with H264 AVC.
What's strange, it is still available and works perfectly fine with H265 HEVC when encoding to 4K although... YouTube can't process HEVC :/ Any idea how to reset it in PowerDirector to use it again?

BTW. I am using NVIDIA GTX 1060, 6GB VRAM with latest drivers.
