Did the graphics driver ABI change in Win 10? If not, what's the problem? So if Intel is not willing to support PowerVR GPU, we still have old tested driver that works under Win 10, right? So it's more about MS' willingness to test newer versions of Win 10 for compatibility with last Clover Trail drivers. They can probably dedicate 5 people to do that without experiencing significant dent to their revenue and the one employee/multiple revenue streams philosophy they adhere to, right?
