I expressed myself badly finally especially "google translate" My BI is well registered.
I mean there was no video recording.

I have tried all types of GPU acceleration and restart every time. It works since my GPU goes up to around 20% but no matter which accelerator I choose, my CPU stays at around 30%, so I don't see any point in using the GPU accelerator

What I do not understand is that I activate or not the hardware acceleration my CPU remains at 30% when it should drop since the GPU takes over a bit. While my CPU stays at 30% and I have more GPU consumption.

Everything is configured to consume a minimum. There is no recording.
I don't understand why when I activate hardware acceleration my cpu always stays at 30%

I am in a super simple configuration at best, no registration.

Hello, I just acquired Blue Iris 5, I configured my 6 cameras and I find that my Cpu is really high even with GPU acceleration. My PC : i7 9700K @ 4900mhz, 32g DDR4, 2x1to M.2, RTX 2080 My CPU usage is 30% and my GPU is 20% (NVIDIA NVDEC). If I disable GPU acceleration my CPU stays at 30%. And here ...
