The beta will allow developers to dump the chip's maths functions on the GPU and pen code that use the GPU better.
According to Arstechnica, the idea is a bit different from ATI's "close to metal" idea which opens up the low-level ISA so that their graphics products can be programmed directly in assembly language.
But the main thing is that the two methods are so different that you will have to opt for one or the other. This means that both ATI and Nvidia will be locking developers into their hardware.
The big idea appears to be that if punters are forced to use their standards then there will be no room when Intel enters the market. ยต
