Thanks for posting your system info - the GPU should support OCL. Can you do me a favor and go to Edit > Preferences > Performance... and click on the Advanced Settings button under Graphic Processor Settings? There's a checkbox in those preferences that allows you to enable/disable OpenCL. Is it enabled on your machine? If not, can you enable it or is it greyed-out?
My guess is that the system is using the Intel HD 4000 instead of the GeForce 660M as the primary GPU. If you can force it to use the nVidia gpu full time, I suspect that OCL will work for PS.
Yes Adam, the "Use OpenCL" checkbox is on. It is not greyed out. I also made sure PS was using the NVIDIA GPU. On my machine, I use the NVIDIA Control Panel to do this. I also tried right-clicking photoshop.exe, and selecting "Run with graphics processor->High-performance NVIDIA processor (default). Note that I have no problems with any other programs using these methods.
If OCL is enabled in preferences then it should be in use. My guess is the poor performance is due to the fact that both GPUs are being recognized by PS. Have you tried disabling OCL and comparing how long it takes to do that same blur on the same image with it enabled vs disabled? You can re-run the filter with the same settings by using cntrl-F.
Is there a way for you to disable the HD 4000 gpu?
Shouldn't the application detect both GPUs and use the most able one? I just tried disabling OCL and the filter performed much better, and used multiple cores (Task Manager showed CPU usage at ~65% when adjusting Field blur size).
I don't think there's any way to disable the HD 4000. I think I looked in the BIOS before, but I'm going to try right now.
Where do you have your monitors plugged in? Could try having nothing plugged in the motherboard video ports and all monitors (if you have more than one) plugged in the graphics card.
I am surprised you can't switch on board graphics off in BIOS, what motherboard do you have? You don't have one of those crippled BIOS some of the big box shifters install do you?
Was able to get into safe mode and re-enable intel graphics. Dave, this is the laptop I have - http://ca.msi.com/product/nb/GE70-0ND-032US.html#?div=Specification
I have just tried using PS with just the laptop monitor, same results. I guess I do have a "crippled" BIOS.
Hi Chris, OpenCL seems to run fine using NVIDIA GPU on a lot of other software I've tried. For example, all the samples here - https://developer.nvidia.com/opencl
It even works with WebCL - http://webcl.nokiaresearch.com/
The samples are able to enumerate both devices no problem, and you can switch with a drop-down box which OpenCL device you'd like to use.
I read the comments and i think you are using a MSI GE60 right? It has a GPU boost problem. So MSI published an update for this. Go MSI's website and find your product. It should be like this: http://www.msi.com/product/nb/GE60-0ND.html#/?div=BIOS&nbos=Win8 64 Read the description and update your BIOS. I hope it will help!
