When you are playing on Black Ops 2 single player, multiplayer, or zombies, any reticles on any red dot scope does not show. This glitch is present in Intel HD 4000 Graphics driver 15.28.12.64.2932(9.17.10.2932). It is also present in Windows 7 or Windows 8. This glitch was also present in the Nvidia graphics driver, but driver version 310.90 has succesfully fixed the glitch on all Nvidia based GPUs, which leads me to believe this is a graphics driver issue. Here is a youtube video that clearly shows the glitch in action on HD 4000: Missing Reticle Black ops 2 NEED HELP PC - YouTube
Any help on the problem would be great, as I have tried everything.
