If you notice redrawing errors and you suspect multithreaded compositing to be an issue, you can turn the feature off in Preferences > Performance.

While there are many reasons that documents might become less responsive when being worked in Photoshop, speeding up compositing between 100% and 250% with multithreaded compositing goes a long way toward ensuring Photoshop can be as responsive and fluid as it needs to be. Multithreaded compositing helps CPU and GPU-based compositing tasks work faster by subdividing computing work into smaller parts that can be run in parallel, often faster than they could be computed in a single 'thread'.

You may notice various slider adjustments not updating the screen as fast as they used to before all those layers and effects were added. Running Photoshop on underpowered or unsupported hardware-for example, on a computer having an incompatible graphics processor (GPU), may result in performance issues.Īdjustment layers, layer masks, blending modes, filters, styles, and effects each add processing complexity to your document that can chip away at Photoshop's processing speed. The most dramatic way to increase performance is by investing in faster and more powerful hardware. Your computer must meet certain minimum system requirements to run Photoshop optimally. The easiest way to improve performance, without spending money, is to set your Photoshop preferences and fine-tune its features to take advantage of your work and the type of files you typically work with. There are four primary ways to affect performance in Photoshop - Optimize your hardware setup, Optimize your operating system for Photoshop, Set performance-related preferences, and Fine-tune Photoshop features.

Every user's setup is unique and may require a different combination of techniques to get the most efficient performance from Photoshop. From the suggestions documented in this article, consider which ones to implement within the context of your computer setup, the types of files you use, and your particular workflow.
