It's been seven and a half years since Valve first released Proton, a software compatibility layer that allows games developed for Windows to run on Linux-based operating systems, such as SteamOS. Since that time, Proton has been regularly updated, and the latest v11.0 beta release packs a whole host of fixes for games. However, Valve has also quietly dropped another version, exclusively for PCs with an Arm64 processor.
One sharp-eyed Redditor spotted this and gave it a go, with mixed success, but if you head over to SteamDB, you can see the update for yourself. It's worth noting that this is very much a test build, and it's reportedly quite wonky donkey, but with a label of Proton 11.0 (ARM64), it's blatantly obvious what device this version is for.
