Virtual reality (VR) uses a headset with built-in displays, motion tracking and software to put you inside a 3D world that responds as you move your head and hands. If you’re curious about VR gaming, the main decisions are what type of headset to buy and whether your computer can run it. This beginner’s guide covers how VR works, the kinds of headsets, what kind of PC you need and what to expect.
How does VR work?
A VR headset places a screen in front of each eye and tracks your head movement, so the view changes as you look around. Most systems also include handheld controllers that track your hands, which lets you grab, throw, aim and interact. Together, the display, tracking and software create the feeling of being inside the game.
Types of VR headsets
There are three broad kinds of headset, and the right one depends on how and where you want to play.
- Standalone headsets have a computer built in, so they don’t need a PC or console. They are the simplest to set up and the most portable, but their graphics are limited by the hardware inside.
- PC-connected headsets link to a computer, which does the heavy graphics work. They can offer the best visuals and the largest game selection, but they need a capable PC and a cable or wireless connection.
- Console headsets are designed for a specific game console and work with that platform’s games.
Many standalone headsets can also connect to a PC for more demanding games, which gives you the best of both.
Room-scale or seated?
Some games are played standing in an open space where the headset tracks you walking around, called room scale. Others are designed to be played seated, such as racing and flight games. Before you buy, check how much clear floor space you have, and make sure the headset supports the style of play you want.
What kind of PC do you need for VR?
If you choose a PC-connected headset, the computer matters as much as the headset. VR needs to render two images (one per eye) at a high, steady frame rate, which takes much more graphics power than a regular game. A low frame rate in VR isn’t just annoying. It can make you feel sick.
When you check a headset’s requirements, look at these parts:
- Graphics card: the most important part. Pick a card that meets or comfortably exceeds the headset maker’s recommendation.
- Processor: a modern multi-core CPU helps keep frame rates steady.
- Memory: 16GB of RAM is a comfortable target for many people.
- Ports: make sure the PC has the video output and USB ports the headset requires.
- Operating system: check that the headset supports your version of Windows.
Compare the headset maker’s current published requirements with your computer, and note that “minimum” means it will run, not that it will run well.

What can you do in VR?
As with regular games, there is plenty of variety:
- Rhythm and fitness games that get you moving.
- Shooters and action games where you aim with your hands.
- Racing and flight simulators, where a headset puts you in the cockpit.
- Social and multiplayer worlds where you meet friends as avatars.
- Creative, travel and learning apps, from 3D painting to virtual tours.
Tips for new VR users
- Start with short sessions. Some people feel motion sickness at first, and it usually eases as you get used to it.
- Clear your play area of furniture, pets and breakables.
- Adjust the headset so it sits comfortably and the picture is sharp.
- Take breaks and stop if you feel dizzy.
Is VR worth it?
Gaming in VR is engrossing, and many people quickly lose track of the room around them once the headset is on. It does cost money, since you need the headset and, for PC VR, a computer strong enough to power it. If you have the means and the space, it is one of the most immersive ways to play.
