With the Nintendo Switch, they conducted the series as an experiment. Steam and other third-party software were pulled onto a not the most modern device
Nintendo Switch has become a participant in Geekerwan experiments. The blogger tested Android, Linux, it even went as far as installing Steam and testing heavy PC games.
Genshin Impact performed horribly (they once announced a Switch version of the game; now I understand why they don’t mention it), but Honkai Star Rail went surprisingly well – over 40 FPS.
Geekerwan also tested several emulators, such as the PlayStation 2 and PS Vita – they generally worked, but the emulators are far from perfect and some games may fail / they lack the power of the console. Nothing worked with the Switch emulator on the Nintendo Switch, it didn’t work.
Also, PC games were tested on Linux-Switch: in Titanfall 2, sometimes you could observe unstable 20-30 FPS, the sound was jerky – if you cut it off, you can play it; GTA 5 ran at ~5-8 FPS.
Geekerwan was able to successfully launch God of War (2018) on the Nintendo Switch. There is no need to talk about high FPS rates, unstable ~ 10 FPS.
