Update 2: I get a similar score with the patch. And luxmark only sees my cpu as being available. So I wonder if it's more related to Preview than OpenCL? Maybe the smbios makes a difference?


I was wondering same thing... But Preview app calls QuickPreview framework - so maybe problem is there... maybe QP framework from ML will work???

It would be cool if there was a command we could use to restart the OpenCL framework... I'm also curious about the CPU usage.


This is interesting...

After opening preview my GPU clock gets locked at 1.08 GHZ

I then ran Luxmark and got this during the benchmark.

This is the benchmark score I got.

After the benchmark it went back down to 1.08 GHZ

Here is my lowest clock state.

I get the same luxmark score when starting from a "non-stuck" state as I do from a "stuck" state.

Also the clock remains stuck at 1.08GHz after running luxmark. So I guess more confirmation it is OpenCL  -_-


In any case I guess my GPU is not stuck at its highest state because it can go a little higher...


With this patch LuxMark wont start.. because patch kills OpenCL ( read the first page of patch ).

What i find that for example Photoshop uses OpenCL - after patch PShop don't find OpenCL support at all - works with CPU.


This is not perfect solution... what i see nice about it - is that your gfx card wont be stuck at high frequency, less heat and power consumption.

For people who don't care about mentioned they just need to stop using quick-preview and instead Preview apk to use something like Xee or similar.

Hope that Apple or Nvidia will fix this annoying thing. I'm not sure that this bug can be found on real Mac-s.

Here is a temp. solution!


tested on my gtx650ti no more sticking at high frequency after preview JPG image.
