DailyTech heard from ATI that volume availability of ATI's physics solution could take 9 to 12 months:
Dave’s reply was that we won’t see physics in volume (i.e. hundreds of thousands of cards being used for physics) and therefore a material revenue stream from physics for 9-12 months (i.e. another 3-4 quarters) as that’s when there will be some substantial volume of ATI graphics cards being used for physics purposes.
ATI GPU’s that support physics acceleration are already in retail (i.e. the X1900 and X1600 series of cards for example). All that’s required is a driver update that enables physics processing, and more importantly, game content which we expect around the holidays. We’re very likely to see revenue from physics before 9-12 months, but as Dave said it won’t be in volume, it will likely be early adopters.
Willis claims content for ATI physics will be available this holiday season already. However, there is no word yet on the driver other than it is "several weeks out."
