Can you check chrome://gpu and make sure that Video Decode: Unavailable does not appear? Video decode should be handled by your GPU, not the CPU. If this is Linux, then you might not be using the GPU at all, which would explain both symptoms.

Hardware protected video decode and out-of-process rasterization are the only ones unavailable. Everything else is Hardware accelerated. Another thing I notice is that GPU stays a steady 20% and rarely every shoots up, which I believe is what contributes to video player lags. No matter what I try in Windows 10 - performance mode, gaming mode it still won't go beyond 20% when playing videos.
