Nvidia is working on these drivers for a long time, and this is one of the reasons why Rene Haas, the top guy in Nvidia’s notebook division, got the responsibility of dealing with Windows for ARM, RT drivers for Nvidia products.
Qualcomm and Texas Instruments, two Nvidia’s main competitors in the ARM market, don’t have the sort of experience that Nvidia has with years of marking Windows drivers for its graphics chips, and this might turn out to be a slight problem.
There is also an indication that Nvidia will be ready for the Windows RT launch in early Q4 2012 (read October) while the competition might actually be late. However, we doubt this since Qualcomm and Texas Instruments are working day and night to be ready for Windows RT launch, as this is a big opportunity for them.
It will be interesting to see if Microsoft can capture any significant ARM based market share with the new Windows. Intel and AMD won’t have any issues with drivers, they already have them as we speak, but they don’t qualify in this Windows on ARM market, as they run x86.
