With Intel having sunset Clear Linux, when it comes to aggressive out-of-the-box Linux performance there is the Arch Linux based CachyOS as the leading contender. Given the recent releases of Ubuntu 25.10 and Fedora Workstation 43, if you are curious about the out-of-the-box performance here are some fresh benchmarks of all three using the Framework Desktop.
its in the review, in the super tux kart benchmark section. under vulkan, their FPS is functionally the same. Under OpenGL, Cachy is somehow significantly faster
I think this cant be some odd anomaly, because that gap is huge
