In Windows Vista, the limitations of using multip

WDDM (Windows vista Show Driver Product: Windows display driver design) in Windows Vista, Microsoft made important improvements. Inside the prior Windows program, based on statistics, most blue display using the graphics card driver related faults: typically when the graphics driver issues at perform, for example, does not acknowledge the GPU acquired the instruction or memory read and compose errors, the Graphics crashes the whole system collapse brought on by a blue screen warning screen, obviously, the penalties from the operate from the user information is irretrievably misplaced.
to solve this lethal challenge, Microsoft Windows XP displays the architecture from the key improvements released in the new Windows Vista display driver architecture WDDM, the design goal is in the driver stage enhance the system balance, in help of new programs, graphics and programs in the same time, present customers with far better performance, even more reliable desktop experience. The fact is, the card will need to possess a WDDM driver for Windows Vista Top quality Prepared certification is a needed condition.


WDDM drivers the positive aspects are self-evident, and now in Windows Vista, video card failure no longer as regular deadlock caused by a blue screen, but a temporary locking program to reset graphics driver to wait , and when finished reload the driver, all user processes might be restored without losing any data.
Then again, WDDM framework there are actually some restrictions, in particular for multi-application cards: multi-card need to utilize the identical WDDM driver, which means that if we would like to use multiple graphics cards Windows Vista, then these two (or block) is at the very least the very same graphics card manufacturers, or at least the same GPU distributors. Specifically, in the previous Windows system, we can use multiple graphics cards from distinct distributors to obtain the multi-display output possibilities can even use Intel integrated graphics motherboard and graphics card (ATI or NVIDIA) to perform with each other with out any dilemma . In Windows Vista, except to abandon the use Areo person interface, in any other case it is going to not be accomplished.
truthful, NVIDIA and ATI have released the corresponding multi-graphics options - SLI or CrossFire - after the force users to stick to one enterprise, many consumers will need to be graphics card makers sensation, WDDM driver for this limitation of forcing consumers don't have any doubt reluctant to become
