Hardware acceleration isn't needed anymore. That was only needed back before substreams were introduced. The substreams allowed other CPUs without QuickSync to be used. For kicks I disabled it and deleted the driver and my system ran fine LOL.
Around the time AI was introduced in BI, many here had their system become unstable with hardware acceleration on (even if not using DeepStack or CodeProject). Some have also been fine. I started to see that error when I was using hardware acceleration several updates into when AI was added.
This hits everyone at a different point. Some had their system go wonky immediately, some it was after a specific update, and some still don't have a problem and HA is decreasing their CPU% usage, but
the trend is showing running hardware acceleration will result in a problem at some point, especially if using CodeProject - depending on the number of cameras using HA and number of cameras using CodeProject, you could be maxing out the GPU.
However, with substreams being introduced, for many people the CPU% needed to offload video to a GPU (internal or external) is more than the CPU% savings seen by offloading to a GPU. Especially after about 12 cameras, the CPU seems to go up by using hardware acceleration. But of course, some will see a CPU improvement by enabling it.
My CPU % went down by not using hardware acceleration. Here is a
recent thread where someone turned off hardware acceleration based on my post and their CPU dropped 10-15% and BI became stable.
But if you use HA, use plain intel and not the variants.
As always, YMMV.
