If you are running Linux and are also a gamer, it is getting much easier to get your Windows games to run under Linux. But an even better option is to install native Linux versions of PC games. I have used many of the tricks listed on this website URL below. They work great, but NOTHING works flawlessly. Not all Windows games play flawlessly on Windows and you can expect the same from Linux. I would also encourage you to make sure you have selected the best hardware to run your games with Linux. Though other graphics options have seen improvement, Nvidia is still the Linux Gold Standard for Linux graphics performance and compatibility.
