5k player 4k movie H264 codec isn't using hardware acceleration on GTX970 GPU

0

The machine I am using: OS Windows 10, 6Gb Ram, NVidia 970GTX and AMD FX6300 CPU, the media player is the latest 5k player display is 4k TV and I am trying out 4k movies, but they lag really badly.

I am enabling Hardware acceleration on 5k player for h264 both encode and decode, but in task manager when I run the movie CPU goes to 95% while GPU is at 15% at most, so I am guessing that GPU acceleration isn't being enabled.

Why would 5k player wouldn't be using GTX 970? How do I debug this further?

According to their website it uses Nvidia Cuda which, I believe, is only available with the full drivers package. Try installing/updating the Nvidia drivers. – None – 2019-12-22T18:49:26.280

@GabrielaGarcia first thing I did, also tried vlc and Splayer, and restarting PC, none helped one bit – Matas Vaitkevicius – 2019-12-22T19:42:41.113

The player that worked for me was Cyberlink PowerDVD 18 Ultra (not affiliated).

Cpu still stayed at 90%+ however GPU went up to ~40% and lagging disappeared.

I have also had installed GeForce Experience and updated drivers, although that didn't do it for other players, still getting like 2fps.
