Under DirectX 12 much further will step in its development concept SFR (Split Frame Rendering) - an approach that is used in a system with multiple graphics cards, where each of them is responsible for handling a certain portion of each frame in the game. If the two cards, the frame is divided in half. If there are three, the frame is divided into three parts. Unlike the AFR (Alternate Frame Rendering), it can reduce the queue depth of the frames and reduce the delay between user action and reaction stage in the game. In addition, it is possible to use the total amount of memory cards, which now do not need to fill out the same information. If the AFR combination of two cards with 4 GB of memory gives a total of all the same 4 GB of memory, then the SFR total volume close to 8 GB, albeit with some reservations.
DirectX 12 work better with asymmetric bunch of graphics solutions - for example, a combination of integrated graphics CPU and a discrete graphics card. In laptops, they often coexist. But the most important feature of the new API - the ability to work in one bundle GPUs rival manufacturers. The video cards based on GPU development AMD and NVIDIA will be able to jointly accelerate the game, or even parallel use its proprietary technology. The quality of symbiosis will largely depend on the game developers that optimize its products under such a combination of cards. Further details will be announced at GDC 2015, which will be held in March this year. Related Products :
