The Chrome team is currently working on Steam game support (Borealis project).
I Hope BG3 will also be added to the list of games playable on ChromeOS with some help from the Larian team.
more info:
https://www.chromium.org/chromium-os/steam-on-chromeos/We’d love to work with you to ensure your games run great on Chrome OS.
If your game is already on Steam and runs on Linux (with or without Proton), you can try it using the instructions above.
If you encounter Chrome OS specific bugs with your game, have particular workflows you’d like supported, or are otherwise interested in working with us, please reach out to borealis-game-dev@google.com.
