Hello reader.
Upgraded pc from a 1600X CPU to a 5950X CPU. From 6 cores to 16 much faster cores, should have been a huge improvement in 4k streaming -
There was. Sorta.
For a while I used stinger transitions that were 1080P. Occasionally they slowed down my computer, but more often they would work OK, but would be a noticeable drop in quality on a 4K stream.
I made all of my transitions in 4K - So I was excited to start using them when I got my computer upgrade.
But OBS would play the 4k Transitions at ~ 1/3-1/5 speed normal - And they would cutout before they finished playing. My CPU utilization never topped 33% when playing these transitions, which I thought was odd. My graphics card didn't increase much in utilization either, and neither did the ram, but that was to be expected.
I wondered, could it be my storage device? Sometimes, the files would be gigabytes in size. Could OBS not read the files quick enough, even though they were on a SSD?
So I got a NVME drive. I installed OBS, windows 10, and put the transition files all on the same NVME drive, which is capable of multi gigabyte/sec speeds.
That didn't seem to fix the issue either.
So I try compressing the file sizes - I used a transparent WebM file type (instead of MOV), which reduced one of the 4k transitions from 2.3 GB to 33 MB. Wow! I thought, this should fix at least some issues. And it almost did. The WebM version of the transition file played about 2X as fast as the MOV file - Awesome! But still not full speed, quite. I'm unsure why this improved performance, because none of my disks ever reached over 1% utilization even with the .mov file, But I couldn't compress the 33MB video any more - My rendering software was incapable of doing so.
So I tried using Nvidia NVENC H.264 to see if that could/might improve anything - nope.
So I'm sort of stuck. My CPU utilization won't ever go above 33%, my GPU and ram don't get effected (much), and my computer still can't play the 4k transparent file at full speed (to be clear, the file has a mask too - so it's going to be even more difficult to play than a "normal" stinger. The dimensions of the file are 3840X4320, 60FPS).
To note - when looking at task manager, it appeared that OBS only used 10 threads (5 cores), and would use no more.
Any help is appreciated and welcome.
