You can play HTC Vive and Oculus Rift games inside your Google Cardboard type headset.
Virtual reality started to gain mainstream attention after successful Kickstarter campaign for Oculus Rift. Several years have passed since that time and many big technology players joined the race for virtual reality. There is plenty of equipment to choose from: HTC Vive, Oculus Rift, Samsung Gear VR, Google Cardboard and many more.
With time, the industry got divided into two branches. Low cost, phone driven headsets like Google Cardboard or Samsung Gear VR and high budget, PC virtual reality headsets running the highest quality VR games available. The latter are usually the highest quality option but at the same time, very expensive.
People who doesn’t want to strain their budget, have to give up on many great VR experiences like: Elite Dangerous, Euro Truck Simulator and many others. Thankfully, there is a solution called VRidge which allows your phone to run PC VR games.
It consists of two parts, an Android application VRidge and Windows server called RiftCat. They communicate with each other by streaming game image from RiftCat to VRidge and sending head rotation data back from your phone to the PC. At the same time, it causes your PC VR games to think that there is a real virtual reality headset connected.
If you have a VR-ready computer, but no VR headset, you should give Riftcat VRidge a try! As long as you have a VR-capable smartphone and some sort of a Google Cardboard to strap the phone to you head, you will be able to play many Oculus and SteamVR games.
You can play all games that support SteamVR/OpenVR standard. There is a support for Oculus Rift as well (with a support of Revive library). A list of known supported games can be found here.
VRidge demo lets you play for 10 minutes. After 10 minutes of gameplay, the game session will disconnect. To get rid of this limitation, there is a one-time 14.99 EUR fee.
