Hi! We've had a couple reports of compatability issues from players using onboard, Intel video drivers. If you're experiencing graphical problems, try switching to the beta channel (right-click String Theory, from your Steam library. Then, go to "properties," and select the "beta" tab. There, opt into the beta from the pull-down menu). If you'd like to leave us a comment, on our store page, about your experience with the beta channel, including information on your video drivers, your input could help us improve String Theory.
