This shows a complete lack of understanding of a simple fact: Not everyone is as wealthy as you. And not everyone stays as wealthy as they were when they bought that games console or once-great PC.In any case it doesn't matter whether you have a £200 potato or a £10,000 dream PC, you'll have adapted to what your hardware can and can't do. For a game where performance was already marginal for a lot of players, taking a step backwards in performance is Not Good for KSP. And for many it will be better to stick with the version that works, if the alternatives are to suffer intolerable lag or to have to throw money at hardware. EDIT: Unlikely. Linux and 64-bit KSP will let you run more memory-hungry mods and may reduce game crashing. The benefits even apply if you have only 4 GB of physical RAM. However framerates are at best going to be equal on Linux as on Windows, sometimes worse, depending on your hardware.
