Virtual reality is… freakin’ amazing.
It’s a truly astounding and engrossing experience – an incredible, brain-fooling trick: you put on the headset and immediately you feel like you are physically somewhere else. Rationally you know that you’re still sitting or standing in your room at home, but as you look around and up and down and see and hear this entirely different environment, rendered perfectly in sync with your head movements, it’s utterly convincing that you’re somewhere else. Maybe you’re standing on top of Mt. Everest or hanging in space over the Earth. It’s not at all like looking at a screen, or even a 3D movie. It’s like being somewhere else.
Yes, you’re wearing this contraption on your head. Yes, you know you can just remove the headset and see again the room you’re really in. And yet, part of your brain is fooled. You hold up your hands in front of your face and you see a virtual set of hands and they move and turn in sync with your physical hands. Just standing and turning around makes you feel like you’re there but then you take some steps, some actual physical steps in the real world – and you find yourself moving in this virtual world. It suddenly becomes all the more convincing and all the more of your brain is fooled.
You crouch down and look around and your perspective changes to match. You reach down and “pick up” an object off the virtual floor. You can’t feel it but you can turn it over in your hands, and can set it on a table or throw it across the virtual space with a simple, natural motion. You step to the edge of a balcony and look over the side and feel the threat of vertigo. You turn away and approach a door, reaching out for the handle and physically pull the door open, looking into the next room. It’s dark as you step inside, so you take out your flashlight and shine it left and right into the corners of the room, trying not to be caught by surprise.
You see a zombie wake and turn towards you, moaning and shambling towards you. He’s just a dozen virtual feet away as you grab your pistol and raise it to fire – discovering you’re out of ammo. Unlike any game played on a flat screen, you feel like you’re actually in the same space with this menace bearing down on you. You have to resist the instinct to physically back away – or to turn and run in panic, yanking out the cord out between your headset and computer. Instead you hold your ground, reminding yourself that this creature so clearly coming at you isn’t real. You eject the empty magazine and physically reach over your shoulder with your other hand to grab a new clip out of your virtual backpack, slip it into the gun, pull back on the slide – not button presses mind you, but physical hand gestures – and then quickly aim (actually raising your arm, no thumbstick or mouse movement) and let off several shots at the zombie to fell it. And yeah, don’t be surprised to feel an elevated pulse or quickened breath after dealing with an intense scene. The immersion is just crazy amazing. And it’s really easy to forget yourself and try to lean on a bannister or a table and get a sudden rude reminder that there’s nothing really there to support you.
Of all your senses, most notably touch is missing. You can’t feel the wall or door that blocks your way, objects that you pick up have no weight to them and what you always feel underfoot is the familiar floor of your home. Each of these do break the illusion, remind you that you’re in a simulation. But just sight, sound and natural physical gestures go a long ways to providing an amazing array of virtual experiences: from defending a castle against animated invaders by shooting arrows with a virtual bow to using a giant slingshot to aim and launch talking cannonballs for maximum destruction in a giant warehouse in Valve’s The Lab, sitting in the cockpit of various airplanes, flying over detailed renderings of any part of the entire world and through live simulated weather in Microsoft’s new Flight Simulator, exploring the frightening dystopian world of Half-Life: Alyx, fighting off walking zombies and leaping headcrabs, or simply walking around the Mos Eisley Cantina from Star Wars or the streets and shops of Stormwind from World of Warcraft.
I’ve been blown away by what it’s like to experience virtual reality right now and I’ve been itching to share the experience with friends over the past few months, but of course we can’t get together with the pandemic still going strong. So I’ve put together a video to share some of the experiences – even though a video can’t come anywhere close to conveying what it’s like to actually be immersed in virtual reality:
A collection of VR experiences
What I demonstrate in that video is the default Steam VR home environment, Google Earth VR, MS Flight Simulator, Valve’s The Lab, Half Life: Alyx, I Expect You to Die, Superhot VR, a World of Warcraft environment and a bunch of Steam VR environments: Enterprise bridge, Hobbit house, Mos Eisley Cantina, Sno Champ and a robot boxing ring.
There’s still so much more to try though: Asseto Corsa car racing sim, Star Trek Bridge Crew co-op simulation, The Room VR puzzle game, Elite Dangerous space sim, The Climb 2 extreme climbing game, Earthlight NASA Spacewalk sim, Keep Talking and Nobody Explodes cooperative challenge, DCS World WWII flight battle sim, Fruit Ninja VR, Star Wars Squadrons space sim, No Man’s Sky, Fallout 4 VR, Borderlands 2 VR, Detached puzzle sim in space, Down the Rabbit Hole puzzle adventure, some short Portal-based experiences, lots of interesting environments to explore, etc.

Hardware: HP Reverb G2 VR headset and controllers
It was the promise of VR with Microsoft’s new Flight Simulator that pushed me to look into getting a proper PC-based VR system. I’ve tried a couple of inexpensive headset shells in the past that let you use your phone’s display and it’s motion tracking ability to get a taste of VR, but that was nothing like this.
What I decided to buy was the new HP Reverb G2 based on its incredibly high resolution displays: 2160 x 2160 for each eye. The result is that you can’t see the pixels or any sort of “looking through a screen door” effect and the image quality is apparently much improved over older headsets, particularly in the center portion of your view. That’s a challenge with VR headsets in general. The center is always sharper than the outer area due to the need for lenses that distort the light from the displays so that you’re focusing on an image a meter or two away rather than the actual physical display a couple of centimeters away.
The audio on this headset is great too, borrowing the speaker design from Valve’s more expensive Index headset: the speakers sit completely off of your ears, unlike headphones, adding to the overall comfort.
The Reverb’s controllers are a bit of a compromise though: in order to eliminate the need for externally mounted tracking modules, the Reverb G2 has four outward-facing cameras to track the position of the controllers. It works okay, but it definitely has blind spots and can’t always tell where the controllers are. Plus these Windows Mixed Reality-style controllers aren’t able to track individual finger positions like the Valve Index controllers. Even better, the Index controllers strap around your palm, leaving you free to make grasping motions without having to hold on to the controllers.
I’m using the HP Reverb G2 with my 2019 16″ MacBook Pro and an external GPU case, first for a 5700 XT but now a 6800 XT, one of the latest high-powered graphics cards. To use the Reverb, I have to boot into Windows (via Boot Camp, doesn’t work under Parallels) but it works well and provides access to all of the many Steam VR-compatible titles as well as Oculus/Rift-exclusive titles via Revive.
