P: Slow UI when using Mac and Custom Display Profile

Hi, my Lightroom classic is going extremely slow with everything I try to do. It’s slow and loads forever just to switch from photo to photo. I updated my MacBook Pro to the latest version and then updated Lightroom to 10.0. I then cleared the caches for video and camera raw photos. None of this has helped

I loaded your display profile, no difference on my end, no slowdown I can detect. Odd, I am at a loss how a profile, no matter how built, would affect the speed of LR. Unless again, something fishy is going on with video cards/GPU. 

And yes, we should take this off line and back into the pre-release forums.

Your profile on my machine has the same slowness as my profile does.

AMD Radeon HD 7950
VRAM (Total): 3 GB

Along the same lines as above, I note that I am using a BENQ SW271 as a second monitor to my MacBook Pro that can run it's own colour profiling app but using the i1Pro calorimeter (in which case the Creator flags say "RD " and using the 4.0.0 specs) These are stored as LUTs in the Display itself, and a similar set created by me using xRite i1Profiler where the Creator flags say 'XRCM' and are using the 4.3.0 specs that I now use as the default profile for the device and with which I get the slow-down.

When I get any updates and get back onto V10 I will try the other (hardware based) set out.

Thanks I probably won't get to your till later or maybe tomorrow.

I am Was DYP in the adobeprerelease forum if you want to discus it further there as I am not sure our NDA permits us discuss updates here.

Here are my settings (which I doubt should play a role) and the simple profile used:

My Video cards:

Radeon Pro Vega 20 4 GB

Intel UHD Graphics 630 1536 MB

I probably will not be able to look at your files until later today. 

Here is my settings and the profile

We could swap settings, the calibration is in the NEC panel, the profile itself does not do much but we could swap them too to see what happens. Or maybe it's the combination of profile and GPU? 

Interesting, On my end Spectraview profiles are NOT fine.

Which make me even wonder more about accessing the Video Card/Driver in LR10 problem.

What application?

Not all display profiles slow down LR. On my end, Spectraview profiles are fine. This issue doesn't affect all users on Mac.
