– SDL cross-platform input support now enables full use of the Steam Controller outside Steam, reducing reliance on Steam Input.
– While SDL coverage is broad, some titles (e.g., certain Game Pass games) may still require Steam Input or wrappers like SteamlessController.
– Long-term potential remains limited by incomplete universal SDL support and the need to utilize Steam Input for full features (back buttons, touchpads, gyro) in many cases.
As I looked forward to the 2026 Steam Controller, one notable drawback from post-launch reviews was the limited support outside the Steam client. Although expected for a device named Steam Controller, the absence of even basic XInput as a fallback is a real downside if you want to use the controller outside Steam games. While Steam Input can be routed to work with non-Steam games (like emulators such as Dolphin) by launching them through Steam, that workaround simply fails for common use cases like games bought through Xbox Game Pass or Microsoft Store.
SDL brings cross platform relief
Fortunately, the issue has now been fixed! Now, in a move akin to PlayStation 5’s DualSense, the Steam Controller is fully supported by the cross-platform Simple DirectMedia Layer (SDL) input library. This means that Steam Input can be bypassed entirely while still enabling full use of the Steam Controller’s inputs outside of Steam. There may be some limitations still requiring manual tools like SteamlessController (for instance, not all Game Pass titles will support SDL inputs) or routing through Steam Input, but SDL enjoys surprisingly broad platform support, especially for emulators and decomps/recomps.
The path forward and remaining hurdles
In the long run, progress still sits on the horizon. Without universal SDL support or the use of XInput wrappers like SteamlessController, Steam Controller remains limited to Steam games. Additionally, while SDL does recognize the back buttons, touchpads, and gyro functionality, fully utilizing any of those added features (which differentiate Steam Controller from rivals) still requires Steam Input.
SDL support as a meaningful upgrade
Even so, solid SDL support for the 2026 Steam Controller— or Steam Controller 2, or whatever name you prefer—goes a long way toward enhancing the Steam Controller as a product. If you are among many users who prefer not to use Steam Input for emulators, for example, the introduction of Steam Controller SDL support is a genuine boon for those workflows.
