Topic: 4K HDR stuttering?

Hi guys, I am running svp based mpv on my pc with Ryzen7 2700,16GB RAM,RTX2070. oc monitor to 72hz so that i can use make 24-72 which is better than 24-60 i think?
all 1080P movies have no problem at all. but 4K is stuttering. i have adjusted processor +6, using GPU in the setting, still no help. only thing to make it play normal is to disable 10bit output.
but I think my pc is capable to play 4K smoothly with 10bit enable?
can anyone help? thanks for your time.

Re: 4K HDR stuttering?

4K/10 bit at very high frame rate is not a CPU perf problem but more like mpv's internal issue with rather slow copying of huge amount of data
60 fps should work. Ryzen 3xxx may also work at higher rates due to higher IPC and memory copying speed

thank you, i will stay with 60fps.

I was managed to play 4k hdr 24->72 when I OC my RAM from 2666CL19 to 3200CL16. Ryzen 1600 af  @ 3800

Never though ram speed matters for HTPC

ryzens were notorious for that because of their architecture.
