Photoshop using ram Even after all tabs are closed

[tonyarockiyaraj]

Hi,

This is tony from India. Using Ryzen 5 CPU, 3200Mhz 16 GB Ram. My photoshop is using about 50% of Ram even when all tabs are closed, also when tabs are opened but not performing anything. Is there any background processing when nothing opened in photoshop? Around 2Gb of ram was used by photoshop when just opened photoshop.

2GB sounds a bit much, I have around 1GB idle here. Otherwise this is normal.

But note that if you have an open image and then close it, the reserved memory will not be released as long as Photoshop is open. That memory will be reused for the next image. This is by design, because requesting it all over again from the OS is much less efficient.

Generally, people are far to worried about Photoshop memory usage. Photoshop is supposed to use all available memory! That's when it works efficiently. Free RAM is wasted RAM.

Raster image editing is massively memory-intensive, and in reality, Photoshop will use much more memory than any installed RAM. That's why you have a scratch disk. All that temporary working data are written to disk, with RAM acting more like a fast access cache, holding only the most current data.

All of this is why it's important to set the memory allocation sensibly. Never go to 100%. The default is 70%, which will leave some for other applications and processes.
