Re: Requirements to run HDR 4k in 60 FPS

HT gives wrong CPU load numbers. "50% CPU load with HT in Task Manager" can mean anything from real 50% to actual 100%.

My CPU shows 45% load with HT and 90% w/o HT with the same settings. But it doesn't mean "HT gives x2 performance boost".

Oh thank you. Interesting, I did not know this. So does this mean on this test:

4K H.265/HDR (10-bit) -> 8-bit
5 / 60% / 85%

The SVP index wasn't high enough for profile settings 1 and 3?

Also would 4k h.265 8-bit video use up the same amount of CPU to interpolate as 4k h.265 10-bit video?

for playing in mpv - yes

nope, considering you're using hardware decoder, h.265 8-bit need the same CPU power as h.264 8-bit

So the SVP index is high enough in MPC-HC for profile settings 1 and 3? That would make sense because the 10-bit is just reduced to 8-bit in MPC-HC, right?
