Imperfections aside, Trinus delivers on the goal of providing you with a basic gamepad-input PC VR experience for a fraction of the cost of a PC VR headset. Trinus really only works well as a solution for playing gamepad games.

You can pair two controllers at once and Trinus supports this, but most of SteamVR’s content really needs positional tracked input to be playable.

While it has a touchpad, it lacks even a basic trigger, and is rotation-only 3DoF, not 6DoF positional. The main thing that prevents Trinus from being a true PC VR solution is Daydream’s controller, however. This introduces artefacts to the image, but it also adds latency because it takes the PC time to encode each frame (encoding is more computationally expensive than decoding if at an acceptable quality level). Neither WiFi nor USB have sufficient bandwidth to transfer the raw image to a VR headset, so compression is used. Contrary to popular belief, this isn’t caused by the wireless transmission itself (in fact, Trinus even supports wired over USB)- it’s actually the compression. Of course, the problem with Trinus and all apps like it is that image quality and latency still don’t match using a real PC VR headset. While this increases battery life, it’s generally effective at smoothening out the experience and bringing it much close to a real PC VR headset. To keep perceived latency low and compensate for dropped frames in the transmission, Trinus incorporates its own asynchronous reprojection on the headset itself. Trinus recommends using a direct connection to the PC
