Browsing + Zooming in and out of a large Pano in Adobe Lightroom Classic today and already had the system run out of memory.

I didn't think this would happen like ever. It was a large pano 6.37 gb in psb format and slightly over the max MP limit at 518 MP, so I reduced it down and things seem to be ok now. 

 

However I have noticed that the Virtual memory size that LRC has is massive - Upon launch straight away before any action it is at around 400GB! 

Only other apps open was mail / canary mail / safari / messages / App Store and activity monitor

No standard 1:1 preview was built in LRC but still I would have expected it to handle it especially considering the capabilities of this machine.

Not sure if Adobe have some work to do with LRC or 4 days is not long enough for all new Mac background tasks. How can viewing a 7 gb image cause a machine like this to run out of memory??

Specs are 16" MBP M1 Max w 64 Gb ram - 4 TB SSD - MacOs 12.0.1 and LRC Version 11.0 - Screen attached - LG HDR 4K Display LG 32UN880 32'' 4K Ergo IPS Monitor

Catalogue is only 460 mb with 15k images

Images show the initial issue - Discovery of the megapixel limit then the virtual size after reducing the PSB file in photoshop to fall well under LRC limit. It still shows virtual memory limit at around 400GB ??
