That is correct, but its not a memory leak actually.
Its how Diablo IV is handling dealing with texture and game assets, loading them into VRAM and then moving them around as needed while you play.
Eventually it loads enough into VRAM and RAM that it can affect some systems. I say some, because not everyone is having the crashing, or getting out of memory errors, but so far every system I have seen and worked on directly will fill up their memory while playing.
But its not a leak. I spent 2 days testing this. If you load a fresh game and monitor the VRAM for the GPU, pop into the game and then just let it sit there. Other than the few interactions as players walk by, the memory will not increase. However, as soon as you move around the world into various areas, towns, vendors, etc, the memory will go up, till the VRAM is maxed, then the game will start shuffling assets in and out. And this is where it starts to act up for some of you.
But despite every system I have looked into doing this, not every system has issues. So while we all agree there is a management of VRAM use issue, I can say it isn’t a leak from what I have tested and observed.
End result is the same. We are having an issue here and D4 needs an adjustment.
