DirectVR is a collection of multiple features that help to make games a better experience when you play them on the headset, it is not linked to the kind of stereo 3D that is available for a game. It can take care of resolution, FOV, settings-tweaks and head tracking. Which of these four potential DirectVR options are available varies from game to game.
Oculus Touch/Vive wands work with almost every game, that is unrelated to DirectVR. You can use the VR controllers to either emulate mouse and keyboard (freely configurable) or a gamepad.
Games that have all four potential DirectVR features are for example the ones below, a lot more have support for at least one of the potential DirectVR features.
