Treyarch recently addressed the bugs reported in the Black Ops 3 PC Beta.
Thanks to player feedback, the PC version of the game is in tip-top shape, sporting many fixes and optimizations that otherwise would have never been addressed.
Included in these fixes are network compatibility, crashing and freezing, and even some laggy mouse controls. While there isn’t a way to test and confirm these fixes work firsthand right now, it’s good to know that Treyarch isn’t giving up on the PC gaming folks in the world.
