Folks, creating a new GPU platform is a very involved and daunting task. Creating a driver set for said new GPU platform is an equally daunting task. To refine them after finding glitches and bugs is to be expected.
It took NVidia, 3DFX, Matrox, ATI, etc, etc years to refine and perfect their GPU's years ago and for those companies who still exist, it's an ongoing process that never ends.
Patience is required. Intel has a great start. I suspect this is the beginning of something good for Intel and the world of technology.
