Eyal,

How did you  "ensure VDPAU is active" ?

How long ago did you have this issue?  As I did not notice the issue,
I am wondering if the issue has been fixed.


Below are some links and notes regards VDPAU that I researched this
morning;

https://en.wikipedia.org/wiki/VDPAU


Video Decode and Presentation API for Unix (VDPAU) is a royalty-free
application programming interface [1] (API) as well as its
implementation as free and open-source [2] library [3] (libvdpau)
distributed under the MIT License [4].[1] [5] VDPAU has been
superseded by Nvidia NVDEC [6].[2] [7]




VERIFYING VDPAU



Install vdpauinfo [8] to verify if the VDPAU driver is loaded
correctly and retrieve a full report of the configuration: 

$ vdpauinfo

Added support for VDPAU Feature Set H to the NVIDIA VDPAU driver. GPUs
with VDPAU Feature Set H are capable of hardware-accelerated decoding
of 8192x8192 (8k) H.265/HEVC video streams.

The card that I purchased was ;

I prefer no fan when possible. Less noise, one less moving part to
fail.

I recently acquired a GT710(*), and it has no trouble with any media.

I just had to ensure VDPAU is active, or else it would max the CPU.
Funny story, without VDPAU some artefacts were visible and I returned
the card for a replacement. Same problem. I then discovered that VDPAU
was not properly installed and fixing it made it all smooth.
