I recently did a fresh install of windows 10 and was using Aparapi with IntelliJ and the driver Windows 10 installed for my nvidia card automatically. It was working flawlessly and showing all the warnings correctly, but after installing CUDA 11.3 (and the Quadro drivers along with it), it doesn't even show the warnings that it fell back to CPU. I figured it was doing this just by looking at all my CPU's going to 100%. Checked the driver of the card details, and it shows OpenCL in there under C:\\WINDOWS\system32\OpenCL.dll and C:\\WINDOWS\SysWow64\OpenCL.dll but do not know what they were previously or if they changed, or if this is an issue.
Is there anything else I need to check or do for this to work again? I tried uninstalling the driver and using the one from windows but it did not work any more. Not sure if uninstalling everything CUDA related would help.
