For the first time ever someone in a video mentioned HBCC which I had to look up; High Bandwidth Cache Controller. In short it allows you to treat some of your system RAM like GPU RAM.
I went looking in the AMD Software and couldn't find it. I've got an RX 6800, is this limited to older cards like the Vega 64? Yes, 16GB is not enough VRAM in 2023 for some games, forget about 12GB. If high end RDNA4 is cancelled I sure as hell hope they make 24GB the new mid-range.

Edited to add a screenshot I found, obviously not from my system.

This was a thing only for Vega and I don't think it ever really did much. What games are you playing that need more than 16GB ?

I had a list somewhere though off the top of my head I can remember two: Sniper Elite 5 and Diablo IV. Not that I even bothered to finish playing D4 last summer. I also have used as much as 10GB of VRAM just with browsers open (I'm a web developer).

Software development is a different matter, a lot of those games just cache memory, CoD games for instance will fill all the available VRAM anyway. There are situations where 12GB are not enough but 16GB nah.
