[LuxMark] CPU not available

I can't select my CPU for OpenCL benchmarks, but GPU's run fine.
What can be the cause?

OpenCL is only for GPU.

You have to install the OpenCL drivers for your CPU.

I have all drivers installed from AMD... what could be missing?

Check for Devices supporting OCL in your system with Geeks3D GPU Caps Viewer

It is a quite old CPU, it may be not supported anymore by AMD driver due to the lack of support for some SSE instruction :idea:

I think AMD dropped the OpenCl runtime for CPU's

Maybe you can install some old version, if you really want to

Well,that is a surprise.

Indeed with GPU Caps Viewer the cpu is not listed.

Bummer what AMD did, don't understand why.

Thanks for the answers!
