Level up your linux gaming: how sched_ext can save your fps

Gaming on Linux has significantly improved over recent years, with better support for user-space frameworks (e.g., Wine, Proton, Mesa, Steam...).

While user-space solutions have their place, kernel-level optimizations can also play a crucial role in further enhancing gaming performance. In this talk, we will explore how scheduling policies in the Linux kernel can improve gaming on Linux.

Focusing on the sched_ext [1] framework, we will show how to design scheduling policies that can reduce latency, improve responsiveness and deliver a smoother gaming experience.
