Given the relatively high VRAM requirements (for recommended of course), just curious if anyone knows of any updates on the rumour that DX12 allows the memory pools from two cards in Crossfire / SLI to be combined into a single larger pool? I.e. two 4GB cards in Crossfire / SLI would effectively yield an 8 GB of VRAM.
Really, I'm just looking at any excuse to keep from switching my crossfire 290s to a single card...
DX12 allows for split frame rendering, so yeah. This would essentially allow for memory pooling, since each graphics card would only need to render it's own vertical half (or whatever) of the screen. This wouldn't scale perfectly, as you'll have some overlap since both GPUs would need to load any textures along the join, but it will be better than no memory scaling at all as we have now. It will also iron out microstuttering.
Hopefully Quantum Break will be supporting DX12's fancy multi GPU features. With it arguably being Microsoft's showcase DX12 game (and since I've got 3 GTX980s with 4 gigs of vram a piece) I sure as hell hope so.
Here's an article on DX12 multi GPU support:
