How do I disable OpenCL Compute Acceleration (Hardware Acceleration)?

[Leigh]

If you're having issues launching Affinity V2 and you suspect that OpenCL compute acceleration is causing the issue. you can force the app to disable OpenCL on launch.
 

1. Clear User Data Method

Launch the app with the CTRL key held down. When the Clear User Data window appears, make sure the only option selected is Disable Hardware Acceleration and click Clear. The app will now launch without Hardware Acceleration enabled.

2. No OCL Flag Method

Using the --no-ocl flag will disable OpenCL for this and subsequent launches meaning you only have to use --no-ocl once and is not necessary for subsequent launches.

MSIX / MS Store 

To use the flag, press the Windows Key + R on your keyboard to open the Run dialog and then type CMD and press Enter. This will launch Command Prompt.

• Affinity Photo: Type in %LocalAppData%\Microsoft\WindowsApps\AffinityPhoto2.exe --no-ocl and press Enter - the app will now launch.
   
• Affinity Designer: Type in %LocalAppData%\Microsoft\WindowsApps\AffinityDesigner2.exe --no-ocl and press Enter - the app will now launch.
   
• Affinity Publisher: Type in %LocalAppData%\Microsoft\WindowsApps\AffinityPublisher2.exe --no-ocl and press Enter - the app will now launch.

EXE/MSI

To use the flag, press the Windows Key + R on your keyboard to open the Run dialog and then type CMD and press Enter. This will launch Command Prompt.

*Presuming you have the app installed in the default location, type in cd "C:\Program Files\Affinity\Photo 2\" and press Enter. Now type Photo --no-ocl and press Enter - the app will now launch.
