That would break the proprietary Nvidia and AMD graphics card drivers. Just as a start. Device driver universe on Windows may be a blessing or a curse, but entire industries have labored to make it sorta work, and to follow troubleshooting scripts (tech support) when it doesn't. Aside from that, the leading edge graphics card drivers are their own, multiple OS universes. With their own collection of hacks for specific games. I'm not familiar with the current state of high end gaming on Linux, but I believe Windows is still the platform for big game titles.
