Lightroom 12.x vs 14.5

Hi.
I'm curious, as after editing my photos looks 1:1 what gains is it to use lightroom 14.5 vs 12.x versions?
after 14.x my lightroom work has been so slow, i updated from 1080 to 5060ti (1:1 but more vram), updated to 64gb of ram. And well is it just me or the 14.5 is just sooo slow, is it do some ai features? I want to roll back to 12.x as its substantionally faster than this new, good that adoba raised pricesd, but did not raise devs to optimize it better.... same with acrobat reader tho.. .or is it just me and everything is fast?
