I have trouble with playing a 2160p resolution. It's lagging on VLC and MPC-HC (with LAV).
At this moment the best I got is PotPlayer (64bit) with all default, .mkv video on SSD instead of HDD and LAV/MPC-HC uninstalled from PC.
What's intresting on PotPlayer it's almost playable besides the fact that from time to time (in like 10-15s) there will be small slow-motion and audio lag. Right after PotPlayer the built-in Windows10 player is trying to catchup with smth like 15fps show. VLC, 5kPlayer and MPC-HC was completly unplayable (black screen/freeze).
I have GTX770, i5-4690 @3.5Ghz, 8GB Ram, Lenovo L27q-10
@edit it's almost working with K-Lite + MPC-Hc + hardware decoder: dxva2 copyback in LAV, like 30s of smooth video and 3-7 of low fps slowmo. Uhhh.
@edit2 hardware decoder: nvidia cuvid works for like 1m and then 15s of cluttering video (low fps) while audio still smooth, but waits every 3-4s so lagging video can catch up :/

Feeling helpless with this one. :/
