OpenCL Hardware Acceleration unavailable

[totjoss]

Hello,

I've just realized that on my desktop I wasn't using my GPU in Affinity Photo. Unfortunately I can not set OpenCL acceleration because of incompatible hardware.

My actual Windows version is higher than the required version. I've double checked and both Windows 10 and graphic card are up-to-date.

My desktop is pretty old but is still powerful enough, especially for photo editing. Here is my config:

• CPU: i7 860 (4 cores ~3,6GHz)
• GPU: GeForce GTX 780 (3GB)
• Ram: 16GB DDR3

Even though the GPU is getting old too, I'm pretty sure it's quite enough for OpenCL feature, as it is equal to my laptop GTX 1660 Ti's performance (which is OpenCL compatible). Is there a way to enable OpenCL anyway ?

It's not about the amount of power (performance) but about the functions it supports. Please open a command prompt and run the dxdiag command. Switch to the Display tab and give us a screenshot of what it shows, so we can see if it's at the right levels as required by Affinity.

Hello @totjoss

Please have a look here:

The GeForce GTX 780 only supports DX11

Thanks for your quick replies ! Actually it seems that DirectX 12 is on.

Yes, but only feature level 11_0. You need 12_0.

What do you see if you check on your laptop?

[totjoss]

Ohh I see. Indeed, on my laptop it says 12 (12_1).

Hey @totjoss, some of us still can't use hardware acceleration, even with 12 (12_1). My Intel UHD 620 GPU spits the dummy the moment OpenCL is enabled. So I'm waiting for Affinity & Intel to get on the same page and sort it out.
