Daz studio reserved gpu memory

When the render is finished and render window closed, still gpu memory is not cleared or freed. Is it a feature or bug for current Daz Studio? Also is current Daz studio using more vram than previous versions of Daz Studio?

It may have started out as a bug, but considering it's been that way since at least DS 2.3 (when I started using DS; maybe before that), by now it's a feature.
Does current DS use more VRAM? Hard to say, given the 10-12% VRAM penalty imposed by Windows 10 and the ridiculous 4-12k textures and maps some PAs include. If a render falls to CPU, is that due to DS using more VRAM or texture bloat?
If by now it's a feature then any benefit am I getting if I change scene or characters without closing Daz Studio?
If you need the memory, you're better off restarting Daz. Sometimes you have to kill it in Task Manager, too. Yesterday I had Daz hanging around for half an hour in memory after shutting it down normally.
It's my impression that it's being reused in the next render, but maybe not all of it is being cleared.
No. The VRAM that doesn't get released within a minuite or two of closing the preview window and saving the render is not available until you restart DS.
I see about 2.5 GB VRAM used after render is closed and scene cleared using New. Are you saying that if I reload and render the scene it will now use 2.5 GB more VRAM than the first time it was rendered?
Pretty much.
Well I've done some tests now and I can hardly see any difference on my system.
After starting DS VRAM use is 3-400 MB.
Then I load a scene and render it in a separate window, when finished VRAM use is 3845 MB (a few MB more than during rendering).
Then I delete the render and clear the scene with File > New, VRAM use is now 2653 MB and stays there.
I load the same scene and repeat everything, numbers are almost the same. I repeat clearing, reloading and rendering the same scene several times. VRAM use goes op a little bit every time, about 40-60 MB, that's all.
Then I simply render the scene multiple times, deleting the render each time, but without clearing and reloading the scene. There's hardly any difference, sometimes VRAM use increases a few MB, sometimes it decreases a few MB.
That's with the latest general DS release 4.12.1.117, on 10 year old hardware with 8 GB RAM and a GTX 1070 8GB, Studio Driver 442.92.
