If Ps is already making the most of the available RAM and you are happy with the other settings we looked at in part 1 but still need even more out of Photoshop, perhaps this next section will be of use to you.
Some quick tips:
- Quit other applications and then restart Photoshop. This will increase the RAM available to it.
- Also, close any images you are not working on.
- Ensure you have at least 1GB of free disk space while Photoshop is running. (This is required as Scratch Disk Space and the more available, the better)
