Since beta ended I have had NOTHING but a black screen on my BLTC window. Trying to explain it to people was more frustrating than the problem itself. Many people said it was just slow and yadda yadda. I tried reinstalling drivers, the game 4x and a host of other things. I finally figured it out just now and was so excited I had to make a quick video to help others that might have the same problem. Hope this helps!
