During the Black Friday sales, I purchased a 13" Dell XPS (for best travel solution for me) with what I thought was enough specs to handle LR and PS editing on the go. Brought the laptop to San Diego, my first trip with it, and just went through the first series of editing, and I noticed that there's quite a disconcerting lag during PS editing. I thought the following specs would do the job without having to experiencing the lag?
8th Gen Intel® Core i7-8550U Processor 1.8GHz
16GB LPDDR3 1866MHz RAM
512GB PCIe Solid Drive Drive
InfinityEdge QHD+ (3200 x 1800) Display
What's causing the lag, and is there anything I can do about it without having to move up to 15" with higher specs?
