People usually have problems when they have bad hardware, gunked driver installs. As for the overhead of Windows. Linux and Windows benchmarks on games (from many many sites, even places like phoronix) show that framerates on games that have native versions of each are about the same.
So at no point does it make my point moot. Windows does not need any special configuration with the vast-vast-vast majority of games. Many things just work and that does include a lot of older games (btw compatibility with older software has actually improved under 10).
You mis-characterising what I said doesn't negate the fact that many of the things I mentioned are issues in my original comment are real problems that continue to exist (and have existed for many years) and are unlikely in my opinion to be ever be fixed. You and many other pretending they don't exist doesn't make them go away.
