So this is what the wiki says
******************************
Hardware acceleration
If your CPU supports Intel® Quick Sync Video, then you can use hardware acceleration in Blue Iris to reduce CPU usage with any camera streaming H.264.
This is controlled by a single setting. Open Blue Iris Options, then on the Cameras tab, find Intel HD hardware acceleration. Choose the option "Yes (H.264)". Restart Blue Iris for this change to take effect. If you are running Blue Iris as a service, you will need to restart the service, or just restart the entire computer.
***********************************
But I don't see this option, I see Intel and Intel+VideoPostProc and Nvidia CUDA. I have an Intel i7-8700, what should I choose?
