Could someone check if this game uses shared GPU memory?

To elaborate:

While playing the game, switch back into windows, open your Task Manager, click on the "Performance" tab, then click on "GPU 0" (or whichever your main GPU is).

You'll then see graphs for "Dedicated GPU memory usage", "Shared GPU usage", and also the current values for these parameters in the text below.

What would be interesting to know, is if you see any "Shared GPU usage" while you're playing Hogwarts Legacy and your "Dedicated GPU memory usage" is close to 100%.

If your "Dedicated GPU memory usage" still shows room, then you won't see any "Shared GPU memory usage" anyway, so that's not a problem. But if your card runs out of VRAM ("Dedicated GPU memory"), but does not utilize "Shared GPU memory", that would be interesting to know.

We just made a quick test on my lady's PC (on my own PC I have 24 GB of VRAM, which the game never fully utilizes).

Specs: GTX 1660 Ti (6 GB VRAM), Ryzen 5 5600, 32 GB DDR4 RAM, 500 GB SATA SSD, Windows 10. Game played on 1080p with ultra settings, raytracing obviously turned off, no upscaling.

Test procedure: Ran circles through Hogsmeade for a few minutes (since that's one of the most graphically demanding areas in the game), then went into the open world to test some combat situations.

VRAM usage stayed at 5.5 GB throughout. The game must be swapping textures in and out because its VRAM usage on other cards exceeds 8 GB on ultra. We're also definitely looking at ultra textures, my lady is used to playing on "high" and noticed the improvement (this was worth checking because some games simply auto-reduce graphical fidelity when VRAM grows scarce). But no shared GPU memory was used. We experienced occasional stutters when turning around, but not all the time.

I'm running on Medium settings on an 8GB VRAM 3070Ti.
After running about in Hogsmeade and visiting Zonko's I have:
4.6GB/8.0GB Dedicated & 0.4GB/15.6GB Shared in used.
There is 32GB System Memory, so little chance of running out of memory altogether.

It might be worth testing again after several hours gameplay and at high settings, but I'm going out shortly.

Thank you for your checking!
