What is the reason why PS keeps showing loading?
Apr 06, 2025 pm 06:39 PM
PS "Loading" problems are caused by resource access or processing problems: hard disk reading speed is slow or bad: Use CrystalDiskInfo to check the hard disk health and replace the problematic hard disk. Insufficient memory: Upgrade memory to meet PS's needs for high-resolution images and complex layer processing.
