Ok, I’m a little bit in gripe mode here. But, I would really like a developer and/or product manager to explain why Sharpen and Gigapixel are sooo much slower on MacOS than on Windows 10.
For example, I tested Sharpen on my 2015 rMBP 2.5Ghz 16GB machine with R9 370X 2gb video. In Mojave, preview updates are taking almost 2 minutes each. That is unacceptable. In Win 10 version 1809, the preview updates drop to 20 seconds using Bootcamp on the SAME HARDWARE. I can live with 5 minute + renders if I have to because I do that once per image. But to have to wait 110 seconds every time I touch a slider is ridiculous.
I brought my 2012 PC build out of retirement. It has a Sandy Bridge E3-1245 16gb RAM. In 2014, I upgraded to a R9 270X but with only 2 gb VRAM. This old PC outperforms the newer Mac in Win 10! Previews render in 8-20 seconds at most.
I read that you guys use Qt as a cross-platform development platform and that it is much slower on the Mac. If this is the case, I believe you owe it to your Mac customers to redevelop that version or do whatever is necessary to bring the Mac versions closer to speed parity with the Windows versions. Last I checked, the Mac versions cost the same.
