Affinity Photo - Slow & Almost Unusable

[North Visual Studio]

Hi, I've been using AP with Win10 for a few years and have noticed a progressive slowing in the performance of the program, which has got so bad that I might have to move back to PS.

I mainly use it for compositing 3D renders which are 32bit exr's, there are usually 5 to 10 layers. I would open the main RGB layer then use Place to add the remaining layers - this is also a slow process. Simple blending and opacity and not much else is done but it lags so bad when I do anything. Turning Layers on and off (including other commands) has sufficient lag that it's becoming a hinderance to my workflow.

I've attached the Performance Tab settings. There are 4 GPU's, 128 Gb Ram so, it must be something else that causing it.

I love this program and don't want to have to change it, can someone shed some light on this?

Thanks,

N

Does turning off hardware acceleration make any difference?

Hi @North Visual Studio,

I'd also recommend ensuring Affinity is only using one of your GPUs, as multiple cards from different generations may be slowing down the app -

Here you should be able to set the 3080ti as the card that Affinity uses. Please do let us know if this helps

Wow, I turned off Hardware acceleration and followed the steps in your link Dan C - and AP is back to normal!!!

I can't thank you enough!
