    Question about Oculus Quest


    I use Windows 7 as my main operating system. Never bothered with Windows 10, so I am posting this question here.

    I do not yet own an Oculus Quest but was looking at some VR headsets, and thinking about eventually getting one. But I am "really confused" about something that makes absolutely no sense.

    I saw several posts, and read some articles that said you can use an Oculus Quest with Steam VR thanks to the recently added Oculus Link that requires you to attach your Oculus Quest to your PC with a USB 3.0 cable and they require a high end graphics card. This is the part that makes absolutely no sense, and I had computer engineering in college.

    If it is using your Video Card, then it would require an output from the Video Card (such as the displayport connector). If it is using the USB-C connector and doesn't have a direct connection to your Video Card, then the games would be being rendered by the built-in processor and video hardware on the Oculus Quest itself and the video card on your PC and its specs would be meaningless.

    Thats the part that makes no sense to me, can someone explain it?

    Quick and dirty answer

    It is and always has been possible to connect the different bus types within the system, a source can be fed via the graphics processor to the screen and/or other connections on the PCI Bus, it's possible with today's hardware to output high quality video through USB3.1 (USB-C) The Graphics card is connected to the PCI as is the USB Bus These various data pathways used to run to lower limits but are now reaching the same levels so now USB can "talk" to PCI so high quality Video is transmittable over USB

Hello, I have the following Problem: Yesterday I got an Oculus Rift as a present. I installed it with no problem. Since my PC has only one HDMI slot, I had to use an Displayport to HDMI Adapter for my Samsung TV I use as a Monitor. Usually it is connected through the HDMI Slot. Now I had...
Pretty cool, they talk and show how it works in game. It's pretty much like a 3d vision goggles thing.They use team fortress 2 for example. Just though I share this with you guys, I thought it was pretty cool gadget for gaming. P50fvL_EWYY
