Do you realize that it doesn't matter to them if gamers use Windows or not, right? Windows is big on the enterprise side, consumer OS is the least of their worries, and their gaming division doesn't lose anything if gamers run their games on Linux, thanks to steam actually. So no, I don't think that maters...
Not to mention that we're talking about Nvidia and having a shitty ass driver being a bad thing long term for them, not Microsoft.
Nintendo DS, The World Ends With You. That game made a difference in me imo
