APh V2 - not releasing all consumed vram when closing a document

[cgidesign]

APh V2 on Windows 10 64 bit.

GPU: Nvidia RTX 2070 Max-Q notebook

Driver: 517.40 studio

Issue:

When opening a document the GPU's vram usage increases as expected.

But when closing the document only part of the used vram gets released.

Only closing APh releases all the vram.

Is this causing an issue? If not—do not worry

Task Manager doesn't always claim it back and I would not rely on Task Manager as it's not always accurate.

We intentionally keep a small pool of VRAM and RAM lying around as allocations are expensive, especially on discrete GPU's. We keep the small pool of varying common sizes around to avoid the overhead. If another app asks for the VRAM or RAM, Windows will evict our memory into the page file and give it to the other app.

For me it is not an issue so far, because I don't reach the 8GB limit.

But I can say that task manager is quite accurate regarding vram in my case. I can always predict that if it shows vram usage reaching 100% that my other software using the GPU will stop working correctly.

Edit:

I tested further and noticed that once I reach 7.8 GB APh stops consuming more vram. Seems so you have a working failsave in place there.

Anyway, thanks for your reply.
