Affinity Photo very sluggish

[RobKlein]

fewer than 10 layers, normally I can move around, apply brush strokes, etc, but with this latest version, not sure what happened, but the cursor is flashing on and off, like its working, and I have to wait between strokes for photo to catch up.

I also normally can brush off the object to get the feather edge of the brush to affect my selected area, but now, if my brush is not directly over the selected area, the brush stroke does not register. This is quite terrible for me, as I often use just the edge of the brush so its feathered, and now I cannot...

Hi RobKlein,

Can you  try disabling OpenCL from Preferences > Performance? If that sorts it, can you please confirm your graphics card and driver? Doing a clean install if the graphics driver can often sort OpenCL related issues.

[RobKlein]

my system has an integrated Intel HD Graphics 520 card

and an NVIDEA Quadra M500M card

which is preferable for Affinity Photo and Designer?

[Chris B]

I believe both should work with OpenCL but again, will likely be driver dependant. 

If neither of those are working with OpenCL, I would just disable it for now.

I've had the same issue but disabling OpenCL worked wonders! My system has a integrated Intel Iris Plus Graphics 640 card.

My NVIDIA Quadro M500M card is the active one and I disabled Open CL and the problem is gone, thanks.
