This is a known limitation of the current GPU-accelerated version of DVR-Scan. See #12 for some background discussion on the topic.
Any suggestions or pull requests for improving performance are most welcome - will leave this issue open to focus on that area.
I just did a test on a newer 3000 series GPU, and seem to get higher utilization closer to 20%. @sundeepgoel72 which GPU were you using this with? It may help to start collecting some kind of benchmarks from users.
@sundeepgoel72 which GPU were you using this with
Older one : NVidia GTX 750 Ti
any update on this one, Should I buy a new version of GPU? how much frame/s are you getting with a 3000 serials card?
i made a mistake the FAN utilization for GPU utilization: I should watch for the Volatile GPU-Util
I did a recent test with opencv-4.9.0 and GPU GTX 960, the GPU utilization is around 69%.

and a test with RTX4090 with GPU utilization around 25%
hope the info will help
Hi,
Even though I am using MOG2_CUDA , the GPU utilization remains poor (< 5%). How can I improve this and increase FPS throughput?
