DisplayCAL ICC Color Profile make the Mac Pro 2019 is SUPER SLOW!

[Vincent]

BTW (after seeing 1st profile you attached)…why do you use U3014, a widegamut GB-LED, in a color managed desktop OS like MacOS in its sRGB mode?
Unless you do some “factory menu” trick sRGB mode has locked RGB gain controls, like a laptop or an iMac or similar limited display. Go to custom color mode & use RGB gain offset controls.

AFAIK U3014 is not supported by Dell SDK so the only way to use its internal calibration will need of an i1displaypro. So even with the hard work of programming Dell SDK is not an option for one of your displays. Not sure about 27″ UHD support in Dell SDK.

If someone could point me to what I am doing wrong that would be awesome.

Profile shows a white point correction (calibration curves, white input you can see by yourself in Displaycal profile info) although settings shows “as measured”.
Maybe @fhoech can shed light on this issue

Make sure you disable all the Apple-specific “picture enhancement” features in macOS Ssystem Settings under “Display” (sorry, can’t remember what that stuff is called).

Same issue here … i thought that my mac pro 2003 was killed by last catalina update, i move back to Mojave, same issue. As soon as i apply one color profile from displayCAL, all the mac start to be slow, especially CHROME & VS Studio (but not only, all other apps too, but it s less noticeable).

How can i fix it ? i live you re product !
