Hello,
Hevc video from GoPro 9 (4K/60fps) plays with framerate drops on my desktop (win 10, i5-11400F, 16GB, RTX 3060, SSD) in VLC, while the Microsoft Movies & TV app runs smoothly (HEVC Video Extensions installed).
Note that in MPC I also have frame rate drops (even bigger).
I also have a dji drone and its 4k video (also hevc) runs smoothly in any players.
What could be the reason? I am completely confused.
