Nvidia GeForce 1070 GTX (Driver version 398.82 which is the newest).Intel i7-8700K 3.7Ghz (8th gen, coffee lake, newer then Kaby Lake).GoPro Quik is now able to open and edit the video but it's stuttering, using 100% CPU on playback and hard to edit the movie Playback is not hardware accelerated and it uses near 100% CPU. Install "HEVC Video Extensions" from store (Regardless if K-Lite is installed or not): Windows Media Player plays video with both video and audio but it's stuttering.The playback is hardware accelerated as it only used 1% CPU. Installed K-Lite Codec Pack (w/HEVC codec): Windows Media Player plays the video with both video and audio smoothly.Uninstall all codecs, also the "HEVC Video Extensions" from Store: Windows Media Player plays only the sound, screen is black."HEVC Video Extensions from Device Manufacturer" (Free version that works with licence software like GoPro Quik): How can I get Windows Media Player and GoPro Quik to use Hardware Acceleration? When I use the app "Movies & TV" for playing the video file then it uses around 1% CPU and Hardware Acceleration seems to be enabled. I have installed the "HEVC Video Extensions" from Microsoft Store. The CPU usage is going through the roof and it's not using Hardware Acceleration. Playing HEVC H.265 videos using Windows Media Player and GoPro Quik then the 4k 60 fps video appears all stuttering and becomes a slideshow.
