Hi,

When I check the GPU utilization while running openpiv GPU I get values between 20% and 30%. Is there a way to increase this value or does it have any role in the speed of the algorithm?

Best,

Tolga

Please create a GitHub repo with some image examples - we need to learn the problem. I do not use the GPU version very often, and we have not checked it with recent Python and CUDA versions. Please explain which hardware/software you use, and which versions of openpiv-python-gpu you use. We have at least two on GitHub.
