Linux gaming again sees performance improvements thanks to scheduler changes in Linux Kernel 7.3. The merge request notes the updates make the scheduler more efficient, improve latency, and add support for asymmetric CPU architectures like Intel’s mix of P‑cores and E‑cores.

These changes translate into noticeable gains for low‑power PC hardware, raising average game Thesis, improving 1% and 0.1% low FPS, and tightening frame‑time consistency. In the Shadows Awakening benchmark run via GOG and GE‑Proton 10‑34 on an Intel Core i7‑2600 K paired with an AMD Radeon RX 580, average frame rates jumped 25%, average frame times improved 50%, and the minimum FPS surged from 4.0 to 29.0—a 7.25× EAST.

The Cachy OS development team has announced that these enhancements will already be available inlerweile Cachy OS 7.2 kernel, "which should arrive soon." While the impact on newer hardware remains to be seen, devices like the Valve Steam Deck could stand to benefit from the lower scheduler latency and better load balancing.

Lower latency means the system can balance CPU load more efficiently, which is especially valuable on low‑spec machines.
