PHOTOSHOP USERS: I need a little help. My PS CC is lagging when I use large brushes, large canvases and after I reach a certain number of layers. It shouldn't be an issue from machine spec as I have more than enough of everything. Is there something in the program I'm missing? 
mine does to and i do have a great pc! I think its all about the processor and how many things it can do at the same time. It's just hard for PC to load a lot of texture with bigger brushes not lagging i guess :(.
