Struggles when playing back certain 4K files in MPC-HC
When I play back some 4K files, my CPU usage is pinned at 100%, frames are dropped, and the video lags. When I play other 4K files, everything works just fine. I've established that everything plays smoothly when I play 4K H.264 files, but my computer starts struggling when playing 4K HEVC files. This might just be because playing back HEVC is a bit tougher than playing back H.264 files, but my CPU usage doesn't go much higher than 35% when playing H.264, so I should be fine playing HEVC files?
Why MPC-HC struggles when playing 4K HEVC files?
When people try to use the MPC-HC - a software to decode 4K HEVC files, it will try to use the CPU only, while decoding a high definition like 4K HEVC will be an extremely CPU-occupying task. Therefore, if you happen to own a computer that has a lower CPU, then the software - MPC-HC won't be able to decode such videos smoothly. That's why MPC-HC struggles when playing 4K HEVC files.
