text: Performance In 2013, tests by Phoronix showed real-world performance of games on Linux with proprietary Nvidia and AMD drivers were mostly comparable to results on Windows 8.1. Phoronix found similar results in 2015, though Ars Technica described a 20% performance drop with Linux drivers.
  Software architecture
  An operating system based on the Linux kernel and customized specifically for gaming, could adopt the vanilla Linux kernel with only little changes, or—like the Android operating system—be based on a relative extensively modified Linux kernel. It could adopt GNU C Library or Bionic or something like it. The entire middleware or parts of it, could very well be closed-source and proprietary software; the same is true for the video games. There are free and open-source video games available for the Linux operating system, as well as proprietary ones.
  Linux kernel
  The subsystems already mainlined and available in the Linux kernel are most probably performant enough so to not impede the gaming experience in any way, however additional software is available, such as e.g. the Brain Fuck Scheduler (a process scheduler) or the Budget Fair Queueing (BFQ) scheduler (an I/O scheduler).
  Similar to the way the Linux kernel can be, for example, adapted to run better on supercomputers, there are adaptations targeted at improving the performance of games. A project concerning itself with this issue is called Liquorix.
