I’ve been using vMix for a little less than a year, but loved it so much, I had to upgrade my PC. With all the GPU shortages, I ended up going through HP and ordered a very beefy machine, with an Intel XEON 1290P processor and NVIDIA RTX 5000 GPU.
It took me a week or two to figure out that vMix was only using the onboard GPU and not even touching the RTX 5000. I searched to locate some instructions on how to “set vMix to use the NVIDIA GPU”. What found was this post on the vMix forum from 2018:
