Games run faster on SteamOS than Windows 11, Ars testing finds

A clear improvement

As you can see in the included charts, SteamOS showed noticeable frame rate improvements in four of the five games tested. Only Borderlands 3 showed comparable performance across both operating systems, with Windows eking out ever-so-slightly higher frame rates in that game’s benchmarks.

Changing operating systems can lead to drops of anywhere from 8 to 36 percent in some games.

Asus’ drivers helped bring Homeworld 3 to practical parity with SteamOS, at Low graphics settings.

For the other four tested games, the stock Lenovo Windows drivers were sometimes significantly worse than those included with SteamOS. When playing Returnal at “High” graphics presets and 1920×1200 resolution, for instance, changing from Lenovo’s Windows drivers to SteamOS meant the difference between a hard-to-take 18 FPS average and a downright decent 33 FPS average.

Sideloading the updated Asus drivers showed a noticeable improvement in Windows performance across all tested games and even brought Homeworld 3‘s “Low” graphics benchmark test to practical parity with SteamOS. In all other cases, though, even these updated drivers resulted in benchmark frame rates anywhere from 8 percent to 36 percent lower than those same benchmarks on SteamOS.

These results might seem a bit counterintuitive, considering that games running on SteamOS must go through a Proton translation layer for every native Windows instruction in a game’s code. But Valve has put in consistent work over the years to make Proton as efficient and cross-compatible as possible; not to mention its continued work on Linux’s Mesa graphics drivers seems to be paying dividends for SteamOS graphics performance.

Running SteamOS also means eliminating a lot of operating system overhead that the more generalist Windows uses by default. Microsoft seems aware of this issue for gamers and has recently announced that the upcoming “Xbox Experience for Handheld” will “minimize background activity and defer non-essential tasks” to allow for “more [and] higher framerates” in games.
