    Photoshop CC 2017 Unusable with Large Files

    Dakana

      I'm working on a project that's 4000x4000 pixels at 72 DPI and about 16 layers. Usually, when I start working on the file, it's fine, and everything is really responsible. However, when I do anything like change the layer or undo the last action, Photoshop slows down to the point that it becomes unusable, particularly with regards to brush lag.

       

      I've tried absolutely everything listed in the performance optimisation guide and elsewhere in the forums, and nothing works. I am running Windows 10, 16 GB RAM, 1070 GTX graphics card and overclocked i7 6600 CPU.

       

      Any help would be much appreciated!
