How can I find out a log or something where VLC tells me if it is or it isn't rendering the current video using the GPU and why? ![]() Is it possible that because I don't have some kind of codec / driver on my system, then VLC defaults to CPU rendering? And the same question for my browser which runs at better fps than in VLC but still appears to use the CPU only. I don't have any other/integrated graphics cards. the GPU is a gtx 1660Ti, which should be more than overkill horsepower wise, can do 120Hz VR etc, and uses latest nvidia drivers.VLC is set to use hardware acceleration, and I tried all options (Automatic, direct3D 11, directx DXVA 2.0), restarting vlc (and even my PC) after the changes, and no difference.The MP4 however uses 100% of my cpu and stutters as I explained. I got the video in 3 formats: mp4, mkv, and webm, all MKV and WEBM use the same resources (cpu) as in the browser/yt - however, the FPS is lower, definitely at sub 20fps instead of 60fps. Playing the same video in VLC however, uses 100% of my ryzen 5 6 core 12 thread 4.2GHz CPU, and stutters at best and stands still usually. playing this video in the browser on youtube at 2160p 60fps, works just fine with 80% cpu usage on half the cores - still not much GPU usage in my system monitor though.(I think it always uses the CPU for rendering video, regardless of video, because system performance graphs always show maybe 2-5% GPU usage and 30-80% usage on some or all cpu threads) I need some help figuring out what could be the reasons why a pc and/or VLC would use the CPU for playing 4k video instead of GPU.
