Any chance this is in the pipeline?

There is a 1.28 app for windows also with a similar uplift. You just need the OpenCL 2.0+ drivers. Anything after 470 should be sufficient.

You can use a binary/hex editor to change __constant to __global and space-characters near text twiddle_dee in your windows binary file.

That should get your GPU times down about  30% 

 

EDIT: added

You may need to use anonymous platform after the executable has been edited since its checksum does not match anymore.

You couldn't use <dont_check_file_sizes>0</dont_check_file_sizes> in cc_config.xml to allow for the different file size and checksum?

Turns out there is a 1.28

Turns out there is a 1.28 app, just needed fresh work to get it. Apparently the list of apps has not been updated to reflect this, however.

Also I apparently missed the announcement that there were updated apps. Unfortunate.
