Hi guys

 

I have this iMac below

and the latest Lightroom and when I use the adjustment brush to select areas for the adjustment it goes super slow. 

What is going on with, is Adobe going to fix this issue, please?

I have the fastest iMac you can buy and with all the upgrades as you can see. 



Can someone help me please as this is slowing down my workflow massively?

 

Do I have to learn another editing software as this one won't work with large images?

 

Cheers

Try going to Preferences>Performance and unchecking the GPU option. Does your brush speed up?
