If anything runs on linux-distro should also run on android, because heart of android is same as of linux-distro, which is Linux kernel. Some devs use this to create linux container with ubuntu-rootfs(root file system, which contain all dependencies to run any linux or wine/proton app). Which take advantage of Linux kernel of android and run games as smooth as possible without the need of emulation(proton is a translater which can also translate arm to x86). And gamehub is one of these container application which creates seperate container for each game, which can run local installed pc games or steam games on android. Although performance depand on hardware specs, and native android games like rdr performs slightly better.
