I'm trying to watch 2160p (4k 60fps) content on YouTube, however, I experience large amounts of dropped frames... i.e. the video freezes/stutters completely (the sound is fine).
The YouTube example I use: Costa Rica - 4k 60fps - Youtube
If I watch the video in 1440p it plays fluently without any dropped frames. However, when switching to 2160p the video freezes/stutters because of the huge amount of dropped frames (80%), see below.
Hence, my internet is stable and fine (via cable) and I'm using the VP9 codec in combination with HTML5 and Mozilla Firefox/Microsoft Edge (same result). I'm not using hardware acceleration.
My PC specs.:
- MSI H97M-G43
- Intel Core i5-4460 Boxed
- MSI GeForce GTX 1080 GAMING X 8G
- Crucial Ballistix Tactical BLT2C4G3D1608ET3LX0CEU
- Seasonic M12II Evo 620W
- LG 27UK850-W Zilver
- Windows 10 Education (is pro version) - Version 1803 - Build 17134.590
- Nvidia driver - 220.127.116.111 (NVIDIA 417.71)
Hence, in my opinion, it should be enough to watch 2160p videos on YouTube? The CPU is stressed a bit, but utilization is around 80%. GPU is barely running since 2160p content requires a lot of decoding from the CPU.
Does somebody have a clue what is wrong/how to fix it (software setting or is it really the CPU)? Thanks for any information!
