One explanation can be that they managed to botch it the other can be that size of RAW images increased significantly in the meantime. I had no problem running relatively recent LR on i5 with 16gb ram.
(I had problem with their pricing though, so I switched to another (non-OSS) SW that is performing similarly for ~1/3 of the price)
Talking about their licensing practice, I was about to buy a license for LR but their website prohibited me because I'm from their no- support/blacklisted country, so I can't buy. thanks for piracy and FOSS as well.
So, am I correct to understand that Adobe managed to botch LR so badly that PCs with vastly superior processing and IO to what I used back then struggle on basic tasks?
Woah.
