We will see general solutions develop coming from multilateral groups
(OpenCL) and Microsoft (DirectCL?) With a third player coming into the
market in the form of Intel, no ISV will be interested in locking
themselves to any particular API when they have viable multi platform
options. Choosing proprietary solutions will automatically deny any ISV
a significant portion of the consumer or professional computing market.
Why do you think Adobe accelerated Photoshop using shader math?
