Hi everyone,

 

I'm facing a big challange on a MBP PRO 16" M1 MAX with LR.

 

If GPU acceleration is off LR is really sluggish. With acceleration on, LR is really snappy.

 

The problem arises due to fact that, is GPU acceleration on the colors I have on de Dev module are much lessa saturated then on the library module and on the exported images. This renders nearly impossible to use GPU accelartion.

 

With GPU acceleration off develop module and library module colors are perfectly consistent.

 

I'm using a LG 5K display calibrated with Spyder X.

 

Any possible help on this?

Are you running MacOS Ventura beta by any chance? This is a known issue with this beta software and a reason not to use a beta OS on a production machine.

Johan,

 

Thank you !

 

You are 100% right. My bad 🙂

 

I did not reach that conclusion. Never though the OS would be the issue.

 

Thank you for pointing me the problem.

 

I'll wait for october 🙂

First, the preview architecture in Develop is unique to all other modules and the most accurate preview of the data. You should always view previews there and elsewhere at 1:1 or greater and when comparing, use the same zoom for each. 
It is normal to see slight differences at 1:1 but if really excessive, the first thing to try is to disable GPU in preferences; better? If not, you might have a corrupted display profile. Recalibrate the display or whatever you usually do to create a display profile. When given the option to build this profile, pick Version 2 (not V4) and Matrix not LUT. As to viewing Develop module and Library and outside of LR, it helps to soft proof in Develop using the same profile used in Library (Adobe RGB (1998)) OR the profile selected in Export for the edited image. 
If turning OFF GPU works, it's a GPU bug and you need to contact the manufacturer or find out if there's an updated driver for it. This is why disabling GPU is an option as more and more functionality moves to the GPU in newer versions of many Adobe products.
