A Guide to Optimising Photoshop Performance

Many of us have a love hate relationship with Photoshop. It’s an incredibly powerful tool that helps us get stuff done, it is however also undeniably temperamental. At times it can slow down or become unresponsive.

So today I’m going to try and help you optimise Photoshop based on your needs. Taking the time to tweak a few performance settings based on your workflow can make a massive difference.
