Flip horizontal ram usage.

Hi
When I open my file in PS it uses 2.5/3GB of ram.
Every time I use "flip horizontal", PS ads 500-700MB of ram.
Till it reaches the max set amount of around 11GB.
Purge all does not reset the ram usage, closing the file does not reset ram usage.
I have to close Photoshop completely to reset my ram.

I also had contact with Adobe customer service via chat and gave them remote control.
This did not resolve the issue.
I started a post on the forums and at least one other person can confirm this behavior.
I use a clean instal of Win 10 and Photoshop.
Adobe Photoshop Version: 20.0.1 20181029.r.41 2018/010/29: 1197484  x64

This is an age old issue... Photoshop keeps control of ram once it gets its hands on it never to release until closed.... they say its in case its needed again.... LMAO.
You gave control of comp to a rookie who dont know azz from elbow.... this ram grabbing is intended behavoir and has been around since Noah built the Ark.

Yea I already noticed that the knowledge of the support was average XD.

Oh well, still hope someone may have a solution for this specific behavior or that there will be an official fix for it.

For now I'm gonna work around this by simply setting a lower ram budget for photoshop, or not running it in tandem with other demanding software.
Thanks for the reply.

As I have always undertood it, this keeps the document Efficiency as close to 100% as possible. It could be nice to have the abilty to purge RAM per action or to specify some type of upper limit as to when it’s okay to let Efficiency drop.

I just tried this out on my Mac with High Sierra. 4-5 flips of a D750 raw Smart Object layer (that's all) added 2GB to the RAM. That seems to be History, because when I purged History, I dropped 2 GB.

It does seem like rather a lot to keep in RAM, though, as it appears to be roughly half a gigabyte per flip. And that's just with no layers, only an extra raw copy in the Smart Object layer.

But you might try losing History (I know, not a great solution), when it starts to become too much, and see if that doesn't keep you working. I hope this isn't just a fluke with my test, anyway. You're not losing anything more than you would if you restarted PS.
