Oculus Quest 2 vs Rift S for PC VR Is the $299 Oculus Quest 2 a good VR headset for PC VR (desktop VR)? How does it compare to Oculus Rift S? In this post, I’ll discuss how well Quest 2 works for PC VR. I’ll also show how to put together a VR-ready PC for the lowest cost, and how to set it up for both wired and wireless VR gameplay, using Oculus Link, Air Link or Virtual Desktop. UPDATE: now added troubleshooting section if you launch Air Link and all you see is a black screen or the logo appear again and again. Show
Table of Contents: Background and Executive Summary BACKGROUND AND EXECUTIVE SUMMARYOculus Quest 2 is a standalone 6DOF mobile VR headset. It doesn’t need to be tethered to a PC or phone, and doesn’t have any external sensors. Instead, it uses four cameras on the headset for inside out tracking using computer vision. Quest 2 is the second 6DOF mobile VR headset from Oculus and improves on the original Quest with a faster processor, higher resolution screen, larger storage options, and a significantly lower price. Oculus Quest 2 (left) and Rift S (right)Rift S is a desktop VR headset. Unlike its predecessor — the Oculus Rift CV1 — the Rift S has no external sensors, which makes it much more convenient to use. It has five cameras for inside out tracking. Although Quest and Quest 2 were designed as mobile VR headsets, they can also be used for PC VR. But how well do they work compared to a desktop VR headset, such as Oculus Rift S? It may seem that using Quest for PC VR was only an afterthought and therefore it wouldn’t be that good for desktop VR. But the truth is that Quest and Quest 2 are pretty good for desktop VR as well. I have several mobile and desktop VR headsets and I was surprised that Quest 2 can be almost as good as Rift S for PC VR gaming, although it does have drawbacks. Oculus Quest 2’s key advantages over Rift S for PC VR: Oculus Quest 1’s key advantages over Rift S for PC VR: Rift S key advantages and disadvantages over Quest 2 for PC VR: BOTTOM LINE Detail: When using Quest 2 by itself, it has exceptional detail. It is more detailed than Quest or Rift S, which are themselves among the more detailed VR headsets. With Quest 2, there is almost no screendoor effect (you won’t see the individual pixels or spaces between them). However, when Quest 2 is used with Oculus Link, Air Link, or Virtual Desktop to play PC VR games, then it appears a little less detailed than Rift S, as if there was a slight blur, but is still sufficiently detailed. And on my system, Air Link and Virtual Desktop are very slightly less detailed than Oculus Link. Black levels and contrast: Both Quest 2 and Rift S use LCD screens (unlike the Quest which uses OLED) and have similar black levels. In ordinary scenes, the Quest 2 and Rift S contrast is not noticeably worse than that of the Quest 1. However, in dark scenes, such as dungeons or caves, you’ll notice the blacks appear dark gray even without comparing it to Quest 1. With Quest 1, blacks consistently appear black. Godrays: Quest 2, Quest 1 and Rift S all have some godrays, although it’s not as bad as 1st generation headsets such as the Oculus Rift CV1. Note: godrays are the glow that you can see around objects when they are in a dark background. IPD: Quest has full adjustment from 58mm to 72mm. Quest 2 has limited adjustment of three positions: 58mm, 63mm and 68mm. Rift S has a fixed IPD of 63.5mm, although its software can simulate IPD adjustment, up to a point. Comfort: Rift S has a halo-style strap with a pad that allows some of the weight to rest on your forehead. For a majority of users, it is more comfortable than Quest 2’s fabric strap. However, Quest 2 does have an optional halo-style Elite Strap that has similar comfort. All three are front heavy and I experience strain on the back of my neck after using them for around 30 minutes. However, when I use a counterweight such as a battery, then there’s no issue. Audio quality: Rift S’ speaker is noticeably weak and tinny (explosions will sound like they come from a toy speaker). Quest and Quest 2 both have decent audio quality. You can get even better quality by using headphones (all three have 3.5mm headphone jacks). Quest and Quest 2 can also
use the HTC Deluxe Audio Strap for good quality audio. MINIMUM PC REQUIREMENTS FOR OCULUS LINK, AIR LINK or VIRTUAL DESKTOP (updated April 28, 2021)When you are using Oculus Quest 2 to play PC VR with Oculus Link, Air Link or Virtual Desktop, your PC has to not only play the VR game, but also has to stream it at the same time to the Quest, therefore it will require a more powerful graphics card. See the list of compatible cards here. As of 2021, the most affordable graphics card that can work with Oculus Link or Air Link is GTX 1650 Super (not just a GTX 1650). Please note that unlike the GTX 1650, a GTX 1650 Super card will require a 6-pin power connector. Note also that when using Virtual Desktop, the more powerful your CPU and graphics card are, the better the graphics will be. Here are the minimum requirements for Oculus Link, Air Link or Virtual Desktop:
The cheapest and probably also the easiest way to get a PC that meets these specs is to get a used PC with i5-4590 or better, 8GB RAM or more, with Windows 10. I suggest looking for one with a tower case. A PC with small form factor can use only half-height PCI cards and the fastest low profile graphics card is the GTX 1650, which is not sufficient to run Oculus Link. UPDATE: due to the rise in prices of cryptocurrency, graphics card prices have now spiked up as well. Another option for a VR PC is to use cloud computing. With this option, you use a powerful PC to run VR remotely. This option is possible for wireless PC VR gaming (see below), but it
cannot be used to run Oculus Rift S. As of February 2021, this option costs $12 per month. More information and demo, see here. FAQ (updated January 2, 2021)Oculus Quest 2 is slightly smaller than Oculus Quest 1
How to Use OCULUS QUEST 2’s OCULUS LINK for PC VR via USB (updated Dec. 3, 2021)Oculus Link is a feature that lets you use Oculus Quest or Quest 2 to play PC VR with a cable attached to your PC. You’ll still need a VR-ready PC but you won’t need to get another VR headset to play PC VR apps. Using Oculus Quest or Quest 2 to play PC VR is very simple as long as you have a PC with the minimum requirements (see FAQ#2 above) and a compatible cable (Oculus Link cable for $79 or Anker cable for $18).
When you enable Oculus Link, the Oculus Home view in your headset will change to the same Oculus Home that you would see on Rift S. You can then launch any game and play it as you normally would. If you want to exit Oculus Link, go to the Settings and click on Disable Link. If Oculus games are not launching correctly, then you should check if Oculus is set as default for OpenXR in the Oculus app. If not, then you need to make it active. You’ll need to use an administrator account to change that setting.
How to Use OCULUS QUEST or QUEST 2 for WIRELESS PC VR (updated January 3, 2021)Quest and Quest 2 can not only be used for PC VR games and apps but it can even do so wirelessly. As of April 2021, the two primary options for wireless PC VR are Air Link and Virtual Desktop. Air Link is designed for Quest 2 but can also be used on Quest 1 if you sideload an unofficial app (instructions below). Alternatively, both Quest 2 and Quest can also use Virtual Desktop for wireless PC VR. What hardware you need for Air Link or Virtual DesktopThe hardware you need is the same for Air Link or Virtual Desktop. In addition to a Quest 1 or Quest 2, you’ll need a more powerful PC (see above), a 5ghz wireless router, and an ethernet cable from your PC to your router. Whether you use Air Link or Virtual Desktop, you need to connect the PC to your 5ghz router via the ethernet cable. Option 1: Air Link on Oculus Quest 1 or Quest 2How to install: Step 0: Make sure you’ve installed the Oculus app for PC, then Steam, then SteamVR (available on Steam) on your PC if you haven’t done so yet. Step 1: Update Oculus desktop app to version 28 or later. Step 2: Update Oculus app on your Quest to version 28 or later. Step 3: under Settings, go to Experimental Features and toggle Air Link on. If you don’t see the Air Link option, reboot your Quest 2. Alternative for Quest 1 with older app version: With firmware version 35 or later, you should also see Air Link even for Quest 1, but if you cannot find the Air Link option, you can instead sideload Air Link Connector. If you don’t know how to sideload via Sidequest, see below or see more details here. How to use Air Link: Note: As of version 35, Air Link doesn’t have to be toggled on the Oculus desktop app anymore. On older versions (e.g. version 28), Air Link had to be toggled on (under Settings … Beta). Step 1: Connect your PC to a 5Ghz router (such as this) via an ethernet cable network is 5Ghz not 2.4ghz. Step 2: Click the Oculus button to bring up the menu, then click on the Wi Fi icon to bring up Quick Settings and select Air Link. Click on the Air Link button to launch Air Link. You may have to confirm the connection on your PC screen. If you can hear sounds but you only see black, see Looping Error below. Step 3 (only for Air Link Connector): If you installed Air Link Connector, here’s how to use it. Under Apps, click on the dropdown arrow on the right side and select Unknown Sources. This will reveal sideloaded apps. Click on Air Link Connector and click on the button with your PC’s name on it. Option 2: Virtual Desktop on Quest 1 or Quest 2An alternative to Air Link is Virtual Desktop. Compared to Air Link, Virtual Desktop is able to run on lower end PC hardware because it has more settings for decreasing the graphics quality. Note that as of February 25, 2021, if you use Virtual Desktop 1.20 or later for Oculus Quest, then you will no longer need to sideload the patched version. How to install: Step 0: Make sure you’ve installed Oculus app, Steam, and SteamVR (available on Steam) on your PC if you haven’t done so yet. Step 1: Purchase and install Virtual Desktop 1.20 for Oculus Quest (available on Oculus Store) on your headset. Do not purchase Virtual Desktop for Oculus Rift. Step 2: Download and Install Virtual Desktop Streamer on your PC. Make sure to install Steam VR first before you install virtual desktop streamer. How to use Virtual Desktop wirelessly: After following the steps above, you are now ready to use Virtual Desktop wirelessly. – Connect your PC to your router via ethernet cable. If you encounter a “Headset not found” error,
try these: How to use Sidequest to sideload Air Link Connector or other appsAir Link should now be available even for Quest 1. However, if you cannot find Air Link or it Facebook disables it, you may need to install Air Link Connector. Here is how to sideload Air Link Connector, an unofficial app to enable Air Link on Quest 1. You can also use this same process to sideload other apps that are not on the Oculus store. You’ll need: Step 1: Install Sidequest. See steps below or watch this video by Cas and Chary.
Step 2: use Sidequest to install Air Link Connector APK on your Quest. On Sidequest’s menu bar, on the upper right, click the icon with the down arrow to install an APK and select the Air Link Connector APK that you downloaded. You’ll see a red dot on the menu bar indicating that it’s being installed. When the dot turns green, that means the installation is complete and you can disconnect your Quest from the PC. On Sidequest, click this down arrow to install an APKContinue with the section above entitled How to Use Wireless PC VR. Bonus: now that you have Sidequest, you may install other unofficial apps available on Sidequest if you wish. Air Link Black Screen Looping ErrorIf you launch Air Link and you can hear sound effects but all you see is the Oculus logo, then black and it seems to be repeating over and over, then try this fix: After launching Air Link, wait for the shimmering sound, which you should hear after a couple of loops of the Oculus logo. The shimmering sound means Oculus has fully launched. You can then go to your PC and launch SteamVR (I peek through the hole around the nose). When SteamVR launches, you should see it detect your headset and your controllers: If you see your headset and controllers in SteamVR then that means SteamVR is workingAfter SteamVR detects your headset and controllers, just wait a minute or two and you should see the Steam Home environment, where you can launch SteamVR apps. You can also click on the Oculus button and it should bring up the Oculus Home menu from where you can launch Oculus desktop apps. Steam Home environmentTracking Lost ErrorOccasionally, you may get a tracking lost error in the Quest or Quest 2. This is usually not a problem with your VR headset. Tracking Lost is caused when the cameras are obstructed or the conditions make it difficult for the Quest’s cameras to analyze the environment. To fix it, you need to check for anything that is interfering with your cameras, then you need to re-enable tracking. Here’s a short video. If you continue to have Tracking Lost error, see this article for other solutions. Conclusion:For PC VR on a low-end VR-ready PC, Rift S is a little sharper and more crisp than Quest in Oculus Link, Air Link or Virtual Desktop. However, most users will find that Quest or Quest 2 via Oculus Link is generally about as good as Rift S for desktop VR as long as your PC is powerful enough. Quest or Quest 2 also makes it possible to play desktop VR games wirelessly if you have a 5Ghz router. The downside is that the graphics are less detailed unless you have a high-end VR-ready PC. If you’re a PC gamer who wants the best detail, smoothest motion, and lowest latency, I recommend Valve Index. On the other hand, if you want a more versatile headset or if you want a wireless VR experience for greater immersiveness (at the expense of a little detail and motion that is a bit less smooth), then go for Quest 2. Can you play Rift games on Quest 2 without PC?Again, no computer is needed to use the Oculus Meta Quest 2. There are hundreds of games for you to play and enjoy as soon as you get one without the need for any extra devices or fancy PC computers. If you have a VR Ready PC you get more gaming choices to play and explore.
Is Rift S compatible with Quest 2?The Quest 2 controllers can only be used with the Quest 2 and are not compatible with any other headset (including previous Oculus headsets such as the Rift S or Quest 1).
Can the Quest 2 play any VR game?There's heaps of native content available on the Oculus Store, but one of the key features of the Quest and Quest 2 is their ability to also play PC VR content as well, while connected to a VR-ready PC — wired and wirelessly.
