I think --auto is the switch for autodetection. This does not help for the use in XNview, since it is not possible to use any switch.

no --auto mode in clguetzli

Got it. AFAIS it has a switch to autodetect the best acceleration (--c).

Is it true?

Note: The solution should work also for ATI/AMD VGA cards which support only OpenCL. :-)


clguetzli support these special mode
--c do not use any hardware accelerated but CPU
--opencl use opencl compute ...
