Photo 1.7 Metal supported GPUs on Macs

[Jamster]

Hi - I've just downloaded Affinity Photo 1.7 on my Mac, but the option to enable Metal computer acceleration is greyed out on the performance preferences window. I'm using an old cheese grater style MacPro, but it's running High Sierra which supports metal and has a NVIDIA GTX 680 which is an Apple 'supported' for Metal.  Any ideas why this is greyed out - I think enabling GPU hardware acceleration would improve performance?  For reference - my System Report states the following for Metal - 'Supported, feature set macOS GPUFamily1 v3'.

Thanks

I just checked Preferences > Performance > Hardware Acceleration [Check box to Enable Metal compute acceleration]. I also checked the box under Display for (use only integrated GPU) and then closed and restarted the program. Display still shows Metal grayed out but below the box for Enable Metal compute acceleration, the program lists my GPU display card (AMD Radeon R9 M395X). RAW file seem to be loading faster and modifications seem almost instant now.

I think that I'll have to check this with support as I don't get the option to select Hardware Acceleration and my GPU is not listed.  However it does state in brackets 'No compatible GPU' and I don't understand why as my card supports Metal.  Thanks for checking as it's given me something to compare against.  It sounds like the hardware acceleration is worth having.

As I understand it (which is not that well), in the Affinity apps Metal compute acceleration is only available for some AMD Radeon GPU's Apple is using in certain recent Mac models.

All I know for sure is the NVIDIA GeForce GTX 660M in my old 2012 iMac is not supported.

Hi all,

Sorry for the delayed reply. 

Our developers came back to me and we do not support Nvidia cards at the moment. 

Thanks,

Gabe.
