Upgrading a PC for Oculus Rift isn't as easy as you think

You can make a five-year-old PC VR-ready. But first, read this.


I'll let you in on a little secret. You don't need to build a brand-new gaming PC to use a virtual reality headset. Sure, it would help -- but with the right upgrades, your old gaming rig might be good enough. I spent most of my time reviewing the Oculus Rift with a five-year-old processor, and every game played like a charm.

Still, Oculus doesn't make it easy to use an aging computer. Here's a short list of issues you might face if you take the plunge.

Your USB ports may not work

When I plugged the Oculus Rift into my computer, it told me my USB 3.0 ports were no good. When I went to buy a USB expansion card, it told me those were no good, either. Here are the ones that actually work, according to Oculus:

  • Intel 7-series (Z75, Z77, etc.)
  • Intel 8-series (Z87, H87, B85, etc.)
  • Intel 9-series (Z97, H97)
  • Intel 100-Series (Z170, H110)
  • Intel X99
  • ASMedia 1042A (using ASMedia driver)
  • ASMedia 1142 (using ASMedia driver)
  • Fresco Logic FL1100

What does that mean?

  • If you've got a recent Intel processor, your motherboard probably already has ports that will work.
  • If yours is as old as mine (an Intel Core i5-2500K) they probably won't.
  • And if you buy an expansion card with USB ports, not any old card will do. It'll probably have to be one with that Fresco Logic chipset.
  • Here's the one that worked for me. By some miracle, my best friend had that exact card when I needed one for my review.

You may need a new video cable

The Oculus Rift needs to use your video card's HDMI port. No other ports will do -- and video cards typically only come with one HDMI port, maximum.

  • If you're already using that HDMI port to plug your PC into a monitor or TV (like I was) you'll probably need a DVI to HDMI cable to connect your external screen.

You can only install games on your C: drive, so you might run out of space

Dumb, but true.

  • If you've got a tiny solid-state drive as your Windows boot drive (like me) and a big hard drive for your files, you can't put Oculus games on the big hard drive.
  • If you wanted to install every single Oculus launch game, you'd need over 100GB of free space. (I checked.)
  • Oculus plans to release an update ASAP that fixes this issue.
  • In the meanwhile, you could try a built-in Windows feature called Symbolic Links.

Your graphics card probably needs an upgrade

This should be pretty obvious already, but hear me out: Even if your five-year-old processor is up to snuff, your video card needs to be pretty new.

  • Oculus recommends an Nvidia GTX 970 or AMD Radeon R9 290 at a minimum, and you'll want to follow that suggestion -- those recent GPUs have a variety of improvements that might keep you from getting sick in VR.
  • It's not just about eye candy, but keeping things stutter-free so you can feel like you're in another world.

Your graphics card might mysteriously not work

This probably won't happen to you, but just so you know, when I plugged the Oculus Rift into my personal Nvidia GTX 970, it wouldn't work at all.

  • Even with the latest drivers installed.
  • Even though that same graphics card had no trouble running Fallout 4 on a 4K TV, or powering three separate 1,920x1,200 monitors simultaneously.
  • Nvidia engineers were stumped. They bought three identical new graphics cards and didn't have any trouble.
  • I tried another GTX 970 and it worked fine, too.

Even when everything works, Oculus will constantly remind you that your hardware's not good enough

Now imagine those same words -- "Your computer doesn't meet Rift's recommended specifications" -- floating above your head whenever you pick a new game inside the headset as well. It's a nice warning if your system doesn't work, but it's a little annoying if it does.
