Late yesterday Steam announced official PS5 DualSense gamepad support in its desktop client:
store.steampowered.com
Games with Steam Input API compatibility will hopefully work well with the recently released controller with minimal fussing. Non-Steam titles can be added to the user's Steam library (lower left corner of client); if the game is launched via Steam, Steam Input API-enabled titles should be able to recognize the DualSense.
It remains to be seen if PC game developers will take full advantage of the DualSense's touchpad, adaptive triggers and advanced haptics.
