I recently bought a Razer Ornata Chroma keyboard, and since I installed it, Overwatch has been hit and miss whether it launches, crashes, or all around doesn’t start and closes immediately.
Today, I decided to figure out the issue. I uninstalled display drivers, tried different suggestions I got from this forum, got in contact with support for both Blizzard and Razer, and eventually started deleting programs. When I uninstalled the Razer Chroma SDK, Overwatch finally launched without a hitch.
I can’t be sure if this problem is just my own, or if others have encountered something similar, but I just want to put this information here in case anyone else has encountered issues with Razer software.
