RAM Overload and out of memory (RAM) errors

My Workflow:
I work in the shoe sales industry. I use a 1000x1500px PSD file to scale down and position product photos. I then retouch them using Generative Fill, the Remove Tool, and other features. After that a create a copy backup file with all the photos of certain product, delete all the layers and continue with the next one. The source files I import are large (4480x6720px).

The Issue:
In previous versions of Photoshop (Pre v27), I had no RAM issues and could process a batch of 200 photos without stopping. However, with the new 2026 version (v27), my memory usage hits 90% after doing small batch of about 20-40 photos. Currently, the only solution is to close and restart Photoshop to clear the cache, I can also confirm using v26.7 version of Photoshop (2025) fixes the RAM problem.

Troubleshooting attempted so far:

• Changed scratch disks

• Adjusted max memory usage in Photoshop settings

• Reset preferences

• Used Edit -> Purge -> Purge All (this had no effect)

My Specs:

• CPU: Ryzen 7 5800X3D

• MOBO: MSI MAG B550 Tomahawk

• GPU: MSI GeForce RTX 3090 SUPRIM X 24GB GDDR6X

• RAM: G-SKILL RipjawsV 64GB 3200MHz CL16
