Metal is slowly

[-Markus-]

When I use choose the option Metal, working with affinity photo becomes more slowly instead of becoming faster.

Especially when using inpainting. Especially when removing dust for example (clicking fast and many times with small brush size).

When I use use Open GL, everything runs smoothly, but when I choose Metal, I click much faster than affinity photo removes the dust / repair the spots. So I always have to wait, after clicking 20 times, until affinity photo has repaired all these areas.

When using Open GL, I do not have this issue, and everything is fast (affinity photo repairs faster than I'm able to click...)

I tried all options already in the preferences, but nothings helps, also complete uninstalling and reinstalling does not change anything.

So far, I cannot see any advantage in using metal, and I go on with open GL. Hopefully this will be fixed until Apple switch off Open GL.

Or anything else that I can try...? As far as I understand, Metal should be much faster than Open GL, not slower...

UPDATE:

I just tried the new BETA 1.7.2.146, and the issue disappeared!

It seems the whole application runs faster now on Metal.

The slowly inpainting brush is fast again (I don't know if exactly as fast like on Open GL - difficult to measure - but obviously much faster and nice to work with again).

The batch processing, exporting jpgs from aphoto files, is about 10% faster than on the other version running metal, and faster than Open GL as well.

I measured with stop-watch, because I wanted to know if it's really faster now, or just in my mind; I can confirm it is.

So, I will use the BETA now for working, and I hope it's running stable...

Yes, the current beta (146) for 1.7.2 is noticeably faster for many things on certain computers.

I can confirm that.
