V1.9 and V1.9.1 Overall Very Bad/Slow Performance

[JeffreyWalther]

Hello,

I have to report that Affinity Photo V1.9 and V1.9.1 have significantly worse performance than V1.8.*.

What is really noticeable is that the operation is very sluggish and the changes to adjustment layers are redrawn much slower.
Something seems to be wrong with the memory management.

I have the feeling that the image is reloaded like from a 3.5" disk when you have made a change. 😜
This was not the case in V1.8 on the same machine.

And I don't have to list the problems with the hardware acceleration. 😕

Is it better if you disable hardware acceleration?

Sure, not enabled. With HA enabled, Affinity Photo is not usable at all.

Same here. 1.9.1 very slow on Windows. Simple image and the merge down function took 20 seconds and no better with HA disabled. Just downgraded to 1.8.5 and solved the problem.

With hardware acceleration disabled, there should be no (negative) performance differences between 1.9 and 1.8.5. If that is the case, we should investigate. Please can you attach a file that demonstrates Merge Down being slower in 1.9 (software) vs 1.8.5?

I have same problem it pixelates slightly before opening and when enlarging. 1.9 slower than 1.8.. It's slightly better with hardware off. Using latest windows 10. I do have Designer and have no problems with this.
