The developer says the game runs fast on Steam Deck
The post-launch roadmap says Dressmaker runs fast on Steam Deck. Steam currently labels the game Playable rather than Verified.
Proper controller support is still planned work
A developer response says the tested build does not currently have controller support and that the team planned to look at it after launch. The official news repeats that proper controller support still needs work.
Expect mouse-shaped interactions
Measuring, rotating, precise cutting, sewing, zooming, and placing small accessories rely on pointer-like input. Community layouts may map missing actions, but comfort varies and those layouts are not official support.
Buying advice
If you can only play with a conventional gamepad and cannot use trackpads, mouse, or keyboard, wait for a controller-support update or test within Steam’s current refund rules. Check the store label again because compatibility can change after this guide’s checked date.
