Support PlayStation 5's DualSense controllers has been added to Steam client's beta, although it will take some time for the support to be listed as 'full'.
According to Valve's post on the latest changes to Steam Client Beta, DualSense support addition is listed as partial, due to features yet to be implemented. The company wrote:
- Added initial input support for the PS5 DualSense controller. Advanced features such as rumble, trackpad, and gyro are not yet supported.
If you've been hoping for full DualSense support, then there's no need to worry just yet, because complex features take more time to be implemented properly. For an example of this, look no further than Nintendo Switch Joy-Con controllers, which took a long time to be made functional on PC, but dedicated users wouldn't let up until it worked.
On the other hand, the programmable parts of DualSense's haptic feedback might be a bit tricky to implement, in spite of Valve's suggestion that these features have "not yet" been implemented.
We suppose that this will greatly depend on whether developers choose to implement this feedback on PC, which is where Sony might actually interfere. After all, this is one of the features that is meant to set PlayStation 5 apart from the competition, so we're not sure whether they'd be interested in relinquishing it to be used on PC.
In the same post , Steam confirmed that Xbox Series X controller is no longer showing up as two separate controllers, so we suppose XSX owners won't have to wait that long to have their One Controller to Control Them All.
