Low budget gamer hold your breath Direct X 12 is coming,
your old hardware can gain more performance in gaming, because now days Direct
X 11 only use single treat with
extremely low utilization on the other threads? That’s a problem — with the
kernel-mode driver running on the same thread as the game and the D3D layer,
there’s just not much for the other threads to do.

From image above we can see the
different between in rendering quality & lighting, No word
yet on whether or not that’s caused by DX12′s alpha status.
GPU Support
One of the surprise announcements at the show is that
Nvidia will support DX12 on every Fermi, Kepler, and Maxwell-class GPU. That
means nearly every GTX 400, 500, and 600 series card will be supported.
Interestingly, AMD isn’t necessarily following suit — the company has indicated
that it will support DX12 on all GCN-based hardware, but hasn’t indicated if HD
6000 or HD 5000 cards will be included in that.
With no availability expected until Christmas 2015, AMD
definitely has a window of opportunity to build support for Mantle. The company
will make its own announcement regarding DX12 later today; we’ll update this
post to include that information when available. Bringing the API out on a huge
range of cards is a major win for gaming, but given that Mantle mostly helps in
situation where a powerful GPU is
paired with a low-end CPU, we’d counsel against expecting amazing
leaps on old hardware. Unless DX12 contains optimizations for improving GPU
performance in ways Mantle doesn't address, old cards on modern
software will only see very small increases.
