I have a desktop with these specs,
vmix version 24.0.0.50
amd 2950x
64g ram
nvidia 3070
black magic pci hdmi input card... quad something.


I am getting a gpu overload message after the program is open for a while, after about 3 hours it starts happening. I also have zoom open running a virtual meeting being fed from vmix. I am playing music and showing a desktop capture of PPT with a timer on. Everything is set to 720p 60. Nothing really intense.

I don't know exactly whats going on, but zoom is also freaking out and becoming not responsive. I suspect both these problems are related.

I have 7 percent gpu utilization, 3 percent cpu, so my resources are not strained by any means. I have high performance under the nvidia control panel set, which I changed from normal. I also tried setting the program priority to realtime for zoom and high for vmix

As I close vmix, then reopen it, the overload message stops and zoom stabilizes for a while.

This might be a zoom and vmix issue, I don't know. I need to solve this though. Ill be testing more on this too. Ive used this combo before and not had an issue. I have had a few changes since the last time. I switched from a radeon vii to a 3070, added the black magic quad hdmi, and updated windows, zoom and vmix.

Any thought on this problem are welcome. Thanks in advance for the help

I just finished doing that clean install, cause why not. Still didn't fix the issue.

I did one test that is alleviating the issue, and this is kinda weird. I am using vmix to feed obs, with vmix output 1 using the "external" button, then I take obs and output directly from obs using the obs virtual cam and zoom stabilized. No glitching, no gpu overload. I don't know if this is a zoom issue, or a vmix issue, or just a weird combination. Im going to run this for some hours to see if any issues arise


Im curious if anyone else who has the most updated vmix, and the most updated zoom can try this out for me too. Use the vmix output to feed zoom as a camera.

Gpu and cpu temps are something I was keeping track of. They sit at about 35-40C during use. Cpu and gpu utilization sit at around 20-30 percent gpu and 5 percent cpu.

I had tried to turn off hardware acceleration for zoom to see if that would help. Turning it off or on did not change anything when I tried it.

Rendering time was one of the things spiking when I got the gpu overload messages. But as I was keeping track of my gpu usage through task manager, and a branded gpu monitoring tool, the usage was very low and showed no signs of overloading. Im am currently testing my pc using my work around. This work around feeds vmix into obs, then obs into zoom. Ive been running over 2 hours with zero issues, where I immediately see issues using vmix directly. I am even running harder than I was when I had the issues. Gpu is not overloading, not showing high frame render times zoom is stable.

With my testing, I am pushing my system harder and with more programs and its been stable. Im running effect generators in resolume, outputting ndi into vmix, outputting that directly to another screen, capturing that screen, then creating a layer that has a looping video, screen capture, and the resolume input. My system is sitting at 50-80 percent gpu and 25 percent cpu. Zero instability at this point feeding into obs, then obs virtual cam into zoom.

I can use this work around if needed, but don't really like adding failure points. It seems to me that there is a conflict in the vmix virtual ouput and zoom capturing that output.......I think it might be time for a full uninstall and reinstall of vmix using the current version, and then the 23.xx version if that doesn't work

Thanks for the input so far.
