Photoshop 2024 uses lots of memory - weird colors

I seem to be experiencing the exact same issue. I've a much beefier setup with 64 gigs of ram and an RTX 4090. I still get random freezes, with Photoshop saying not enough memory along with GPU related not enough video memory crashes. The last one shows that in the camera raw editing section and I cant go any further without shutting off the software.

It is interesting that LrC is listed under the GeForce Games & Apps and PS isn't.

@That Girl There just as a test, try enabling this option in preferences and restarting Photoshop to see if it helps, also do you use the Studio or Game Ready Nvidia driver, Adobe recommends the Studio version.

Not the GPU driver. Nvidia just updated it this week

D Fosse, I would agree with you regarding the memory, if I was actually doing intense work in the app. But basically I opened a file and placed an image. CS5 handles memory better. Yeah, I know how the scratch disks work. I have 3 drives on my system. And I set up the scratch disks on two of those drives.

Should I drop the PS memory use down to 50%

It is the GPU/driver. Please post Help > System Info.

Not the GPU. I have a Nvidia RTX 2060. 

Yes, the colors is a GPU issue. Post Help > System Info so we can see your GPU configuration.

The memory usage is normal. Most people don't realize how memory-intensive advanced raster image editing is.

There is no such thing as "enough memory". Photoshop will need more, no matter how much RAM you have installed. That's why Photoshop uses a scratch disk, to write temporary working data to disk. Think of the scratch disk as Photoshop's main memory, with RAM as a fast access cache.

It is very much normal for Photoshop to saturate available RAM very quickly.

@That Girl There for the weired colour issues, this is more than likely GPU driver related, what GPU do you have in your system and is the driver up to date

Have you tried saving your project, closing everything, and restarting your computer?
