Is your PC ready for VR? Find out with VRMark, the virtual reality benchmark, available now. http://www.futuremark.com/benchmarks/vrmark.
VRMark includes two VR benchmark tests that run on your monitor, no headset required, or on a connected HMD. Run these tests before you buy an HTC Vive or Oculus Rift and see if your PC has what it takes to deliver a great VR experience.
After each test, you'll see clearly whether your PC is VR-ready or not. You get an overall score for your PC, which you can use to compare systems, and detailed charts showing how your PC performed.
There is also a free-roaming Experience mode that lets you judge the quality of the VR experience with your own eyes. Take your time and explore each scene in VR or on your monitor.
