VLC stuttering in 4K 10 bpc (not caching)

[Hydrag]

Hi,

 

I hope this is the correct forum.

After my first two threads my 2070 Super arrived today. I popped it in and (thanks again to everyone who helped me here) it worked!

I installed the latest drivers, everything is fine. I did some Benchmarking, the values are perfect and fluid 60 Hz (Monitor maximum).

I also changed the display to 10 bpc.

 

At first I could not find the option in the NVidia control panel, then I switched from RGB to YCbcr422 and I got the option now and switched to 10 bpc.

I hope 4.2.2 was the correct one. HDR works as well although I have turned it off again as I need to adjust the colors for HDR in the monitor menu first and I don't have time for that now.

Now the problem is, I tried to play a movie that is in 4K and has 10 bits and even HDR-10 available.

 

When I run 4K 60 Hz videos on YouTube they look really smooth and they are totally 60 fps, but for VLC mediaplayer you can see a lot of stuttering. It's not like it's not getting the pixels but it's like the picture becomes slower and then faster again, while you don't see any quality drops or something. Now I know, you can increase the frame buffer in VLC, already did that back on my 780 Ti since it was stuttering back then.

But afterwards 4K would run fine. I also tried to copy another 4K movie from my HDD to my SSD to make things faster but still, it keeps lagging and we are not talking about 60 Hz movies here.

 

My question is, did I set up anything incorrectly? Because everything else is running fine. Also I cannot switch to another player unless you can recommend me one. I tried every one that claims to be

free and plays 4K in HDR but none of them worked. They were either stuttering or they would ask for money for every file format. VLC was the only one that worked for me.

 

One thing that could be is that I connected the monitor via HDMI and not via Displayport, but I think the 2070 Super with HDMI 2.0b should be able to play that, as it also produces 60 fps in games at 4K.

So okay, Displayport could be an option here in the end, my cable is broken unfortunately so I will have to order a new one. Still, this should in theory effect any 4K player then but for me is seems like it's only VLC

( I don't bother about installing every other option I had tried before again to test that now).

 

So I hope this fits into here, any suggestions are welcome,

Thank you all in advance and stay safe,

Greetings

 

 

EDIT:

Problem solved, for some reason hardware accelerated decoding was re-activated. Now it runs smoothly
