Becomes slow while editing

Dear Users,

can you help or give me some advice what to do with Lighrtoom Classic slowing down throughout the process of editing photos, so much that it's becoming impossible to use.

I have a computer well fit for graphic work (iMac 4.2 GHz Quad-Core Intel Core i7 Processor, Radeon Pro 570 4 GB, memory - 64 GB 2400 MHz DDR4, Ventura 13.7.1 OS).

While editing photos, LC runs quite well for the first 15 mins or so, but then - especially when I'm using masks, lens blur or a remove tool - the computer fan gets really loud and the program slows down, up to a point when I have to wait 10 or 15 secs for any move to be implemented. It becomes impossible to precisely use almost any of the tools... I'm forced to quit fork for 10 mins or so, so that the app recovers and starts working again. But then the slow-down story repeats again.

My friend adviced me to increase the cache to 40 GB (in the LC settings), which I did. Didn't help. Runs well for the first 15 mins or so, then gets loud, slows down and we're back to square one.

All this makes using LC almost impossible in the long run.

I'd really appreciate your help.

Cheers,

Jadwiga

When you mention that the computer get loud, that's an indication of overheating. When that happens, the CPU slows way down to prevent meltdown. I suggest you take the computer in to an Apple store, describe the symptoms to them and request they check for proper cooling. This sounds like an older Mac and the cooling system could be partially blocked or have other issues.
