While some Linux enthusiasts eagerly recommend users boot their systems with the "mitigations=off" kernel parameter for run-time disabling of various relevant CPU security mitigations for Spectre, Meltdown, L1TF, TAA, Retbleed, and friends, with the new AMD Ryzen 7000 "Zen 4" processors while still needing some software mitigations, it's surprisingly faster for the most part leaving the relevant mitigations enabled.

Recently the open-source AMD OpenGL driver "RadeonSI" enabled OpenGL threading by default for the "glthread" option that has long been opt-in on a per-game/app basis. Along with that has been a number of glthread-related improvements to this code that punts executing OpenGL calls to a separate CPU thread. The Zink OpenGL-on-Vulkan driver has now unconditionally enabled OpenGL threading too.
