Troubleshooting CPU overload in Vmix with 3 cameras and Blackmagic capture card

I encountered a problem when adding 3 SDI cameras through the Decklink Duo 2 to Vmix. Strangely, when each camera is added, the CPU starts to heavily stutter. After the first camera, it's at 5%, after the second, it's at 50%, and after the third, it jumps to 100%. Interestingly, when performing similar actions in OBS, the CPU load is only at 3%, and all cameras work simultaneously without issues. The problem is likely in the settings, and high-performance mode is enabled in Vmix. All drivers are up to date, and connections are correct.

You're going to need to provide a lot more detail than that.
What is your hardware? CPU, motherboard, etc. What video format? What are all the settings on the input properties when you add the camera to vmix? (resolution, frame rate, interlaced, video format)
