Not every virtual reality (VR) system requires a PC, but many of them work best when you connect a high-powered computer to them. The Oculus Quest 2, for example, is a system for virtual reality without a PC, but being able to connect your headset to your computer means that you will be able to access the games stored on your computer that have VR capabilities. Other systems. like the Valve Index and HTC Vive headsets, do require a PC in order to get the best, most immersive gaming experience possible.
Virtual reality is a relatively new technology, especially in the world of gaming, and it can require technically demanding PC builds to run your VR headset well enough to get the best digital experience possible. This is why it’s important to consider whether you have a VR-ready PC before you buy a new headset for your home. Not every computer has the capabilities to run graphics-heavy VR software. You may want to check out other PC builds for VR to see how yours stacks up or consider looking into buying a new computer to fit your needs.
On the other hand, if your computer isn’t up to the task and you don’t want to upgrade, you could always choose to use VR without a PC. An Oculus headset doesn’t need a PC hookup at all, and an HP Reverb can run on a computer with less power if you don’t mind having a lower resolution while gaming.
