4K H265 playback - choppy no matter what I try?
Afternoon, all!
Attempting to playback a 70 gig 4K H265 file, and no matter what I use, the playback is choppy; both video and audio. I'm using a GTX 980 and an i3; settings seem good for everything else, but not when it comes to this file, whether I use VLC, MPC-HD, or Windows Media Center (K-lite codec pack, course.)
Any ideas? Just got my very shiny OLED set up, and everything else is working like a dream. Apologies if I've left anything out!

I'm not sure, but I think your GPU is the bottleneck. Not from the processing side, but it's like too aged. (maybe the bandwidth for this file is not enought, maybe the HDMI type (1.4 or 2.0)... etc).

Found the solution - was actually my CPU
'side-graded' from an i7 I had spare, and it's all fine now.

GTX 980 does not support hardware acceleration of H265, so you indeed need a fast CPU.

Ah! Well that does indeed explain it - thanks so much!
