This is purely from a broken test. Watch the video and you'll see that its not testing with the same power limits.

17w tests are actually 16w vs 20w+ and 35w test is 25w vs 35w

This leads to drastically higher clock speeds on both cpu and gpu as seen in the video and thus higher fps (and power draw, so lower battery life)

Please help stop the spread of misinformation

When testing Kingdom Come: Deliverance 2, Cyber noticed a shockingly significant jump in FPS, with Linux generating ~32% more FPS compared to Windows. This trend follows at lower wattages, albeit with less noticeable differences, and the delta actually plateaus in Hogwarts Legacy to the point that both Bazzite and the Xbox FSE offer the same FPS at 13W. That being said, those frame rates are much more consistent on Linux, according to Cyber, who shows that the FPS graph on Windows fluctuates regularly, while staying mostly flat on Bazzite.

The irony of it considering Microsoft's tweaks to make it a "gaming mode" windows (which results in miniscule FPS gains).

Won't help with titles like Destiny 2 which require Windows.
