Poor AI Detection Speed

I found some of the new drivers did not work well, that might be your issue, I am using the below driver

Driver Results | <dd~ProductName> | <dd~OSName>

Tried that version too. I don’t get why BI has two GPUs to select in the Ui.

I’m currently using BI for 2 cameras. When I select one gpu the one camera is significantly low on ms speeds BUT the other one is now slow.

When I go to select the other GPU it goes in reverse. Now the other camera is fast in detection speed but the first one is now slow.
 
As noted, I also see two GPUs listed, but I only have one. Both are slow. The CPU is even slower, but it's older.

I finally reconfigured everything and I'm now using sub-streams where possible. Still getting 450 ms for detections.

I'm using CUDA 11.7. It works, so I'm not sure anything newer will help? Seems like it should work or not.
 
I am in this exact same boat... Doesn't even seem to touch the NVIDIA card during AI.

What is strange is when I replace a video and turn the AI debug on, I do see the GPU usage go up. But during actual running it seems to stay unused.
