I thought I would give the FLACCL encoder in CUETools 2.1.6 a try since I have a half-decent, semi-modern NVidia GeForce GT 730. When I do, though, I get this message:
Exception: no opencl platforms found
I checked the Windows 10 (1803) "Driver File Details" for my GT 730, and it lists ...\OpenCL.dll and ...\OpenCL64.dll drivers.
They are both version 18.104.22.168 from Khronos Group.
At least Windows 10 upgrades reinstall graphics drivers in a way that OpenCL isn't recognized. Easiest fix is to download the latest drivers from https://www.nvidia.com/Download/index.aspx?lang=en-us (https://www.nvidia.com/Download/index.aspx?lang=en-us) and install them.
Thank you. Manual driver install got it. It is even actually faster. FLACCL encodes faster at level 8 than the cuetools encoder at level 6 :)). I don't know how many times I have gone to the trouble to get something like this to work, and it ends up not making a difference :o.
For the WAV file I chose for comparing, cuetools took ~15 seconds, and FLACCL took ~12 seconds. That is ~23% faster 8) (or, ~20% less time).
