Apparently Asobo are under the impression that the VRAM overprovisioning issue with DX12 is fixed, because the bug report thread was closed and marked as “fixed on live”, which it most definitely hasn’t been.
I started a new thread for it in the bug section for it. I would strongly encourage everyone experiencing the issue to add their info and votes to it to get some attention. Because as of right now it’s considered a resolved issue as far as the devs are concerned.
