Iirc it runs flawlessly. Fox engine is amazingly optimized and even the lowest settings look spectacular in this game. Battery, I think I’ve played around 1,5 hrs on medium settings, 45fps, but it’s been a while ago. Definitely fully playable.

prolly stupid question, but did you update the dock’s firmware?

All devices in the chain need to support Variable Refresh Rate in order for it to work. It might be that a generic USB splitter/dock with HDMI doesn’t actually follow the spec, thus preventing the TV from doing a proper handshake.

Sucks, but true.

Valorant, or, rather, vanguard, on windows 11 requires secure boot to be enabled. And while Steam Deck’s bios supports it, it doesn’t have the signing key generated on the board, so you’d have to go through multiple technical hoops just to get that enabled, and then, after enabling that you’d have to sign SteamOS bootloader after every update to even be able to boot it with secure boot enabled. Going with windows 10 removes Vaguard’s secure boot requirement, meaning you shouldn’t run into vanguard problems and it requires no modifications to the deck itself, especially when booting from external.

Can’t speak about valorant working, because I still haven’t gotten around to reformatting the drive from win11 to 10.
