My friend has an almost identical PC setup to myself, with the same memory (16GB), the same SSD discs with similar free space on all drives, the same processor, Windows 10 etc...but is having real problems with the speed of use.
I have compared all preferences in PS and these are also set the same, including the values for amount of memory to use etc.
On my setup - I select a file in LR to edit in PS and once loaded, check in the task manager it shows that PS is using about 2.5Gb memory. When done on her PC - the system shows over 10Gb being used.
I've checked that nothing else is running; tried multiple images, tried RAW straight from import images, previously edited .tifs etc, but always this huge discrepancy in memory usage.
Any ideas what could be going on?
