I have the Sapphire Duel-X R9 270X graphics card. I want to know if there is a driver or something to do to update my card to run VR or do I need to get a new graphics card?
You would need a faster card really since you would want to be getting 90FPS minimum for a smooth experience when playing in VR. A R9 290x or faster is recommended for a decent VR experience. You can still use your GPU but it will be laggy and choppy (but some games will run better than others)
