BUG Premier Pro clears RAM when I press alt + tab and playback is paused

Premier pro 23.6.0.65. Windows 10.

Premiere Pro Freezes When Alt Tabbing

In the premiere, I edit several videos totaling 10 hours.
In general, nothing freezes normally, even in fullhd it works in plyaback and everything seems to be cached in RAM + video card memory.
But when I make premier pro an inactive window, for example, switch to the browser, I notice in the task manager that the RAM from 15 GB drops to 13 GB, I go back to premier pro and turn on playback in premier pro, wait 5 seconds and playback starts, everything is instant without lags I can rewind moments, watch complex effects and so on, there are no lags and I notice that the memory in the RAM again rises by 3 - 5 GB.

The problem is not with my components. (and I have an rtx 3060 ti + nvme 2tb + 32gb ddr4), but the fact is that when I change the ACTIVE window from premier pro to another, optimization works and clears data from RAM for the program.

By the way, I noticed that if I click on the play button in the playback and press alt + tab on another program and return to premier pro again, everything will work fine for me and there will be no loading of the video into RAM. But if you do the same thing, but when playback is paused, then the RAM will be cleared and you will have to wait again for 5-10 seconds to load into RAM.

I looked through all the settings and forums, but found nothing.
Some optimizer breaks everything.
I also disabled hardware acceleration of GPU scheduling in win 10, didn't help.
I reinstalled the nvidia drivers from game ready in driver studio.

Perhaps the problem lies in this version, that the developers in the code were unable to set the normal priority for the use of RAM.

premier pro 24 also has this problem

It's not an 'optimizer'; releasing memory when PPro is backgrounded is by-design behavior.

When PPro is sent to the background, importers are given the opportunity to "quiet" their connections to the media files referenced from within the project. 

Here are the SDK docs: https://ppro-plugins.docsforadobe.dev/importers/selector-descriptions.html#importers-selector-descri...

Well, when you need to write down some information with word press, you have to constantly wait 5 seconds, which is very annoying. (or create a crutch with playback in the background). It would be more logical if PPro goes into the background after 10 seconds of inactivity, but not instantly

>It would be more logical...

Understood.

The OS notifies applications when the are 'backgrounded'; PPro doesn't have the luxury of going to the background, and then 10 seconds later, deciding to quiet those file connections.

and if there is a need to constantly watch the script and voice over, but at the same time I have to alt tab, will I have to constantly wait 5-20 seconds?

Thank you very much for answering

Unless you were to break up your project into multiple projects (using Productions), yes, that is likely.

note: I am not sure that productions would solve the problem; however, that is one way you could have just one project open (maybe not the project that references all your media), minimizing, the amount of quieting that happens each time you background PPro.
