The Steam Deck’s multitouch screen might be its most underutilised feature. Until recently, I wasn’t even sure whether devs could use it for anything more than simple mouse emulation. But I’ve just started playing “Sky: Children of the Light” on my Deck (which is generally a great experience on Deck, especially on the OLED with 90Hz HDR) and I found that when using a musical instrument, you can actually use the touchscreen to play up to 10 notes at the same time.
This got me curious: Do you know if there are any other games on Deck using multitouch, or is Sky the first one that does it?
I’m not sure if games actually can support multitouch on Linux unless wine supports Windows’ touchscreen APIs, plus by default touch does mouse emulation instead of native touch
The Sky devs managed to do it somehow in any case. Could be the windows touchscreen API.
