4k streaming and recording issues

Has anyone else had issues with OBS not being able to handle simultaneous 4k recording and streaming to YouTube? I was originally able to do this with my older 1080p cameras, but after switching to Sony's BRC-X400s (4k quality), doing both at the same time causes huge losses in frames. The weird thing is that at the bottom of the screen, OBS says I'm dropping no more than 7% of my frames, but the recording or YT stream will be stuck on a frame for a straight 10 seconds before skipping to another frame for another 10 seconds (the audio is seamless).

I dropped the recording quality to 1080p or lower with a low bitrate, and still had the same issue.

I am using two X400s, plugged directly into a Mac Studio. So I should have plenty of CPU and GPU cores. I am using the hardware encoders; 29.97 fps, about 20,000 kbps for streaming, and my upload speed over internet is over 150Mbps.

I have tested everything I can think of, and I don't seem to be overworking my hardware, so I've started wondering if it's a software issue. Any ideas? Thanks!
