Using nvdec really doesn't make sense since decoding 1080p and 1140p videos on cpu has lower energy consumption overall.
I wish Nvidia had a native vaapi support or this project were supporting vdpau instead of nvdec. I guess this is only useful if you are decoding 4k videos all the time then it makes sense to use gpu decoding in terms of saving some energy consumption.
Not the mention cpu decoding at the moment more stable than this implementation.
My old AMD 7950 also had a weird, unecessarily high p state it would go into when decoding video. But it wasnt linux specific, and it also wasnt an issue because it wasnt a 350 Watt GPU.

I'd guess thats because Nvidia clocked the 3000 series so aggressively :/.

Another problem is the missing support for both videoencoding and decoding in most linuxapps: Browsers (Webrtc), Elektron Apps etc. Also Videoencoding and decoding can cause a massive load on the CPU on lowerend (and older) Hardware. GPU offloading is very important in such a case.

At this point Nvidia should really fix their nvdec since as far as I can remember I did not observe the same increased power consumption when decoding and encoding in Windows. I don't know how they are handling their Windows video decoding and encoding but we need something like that.
