  1. the shaders come up every time I play the fricking game for loading!!

    1. Me too. It’s very annoying. I let the update complete each time but the next time I fire the game up its the same thing again.

  2. When the game doesn’t crash on me and I’m not waiting for shaders to install it is super fun. Just hope activision fixes all the quality of life issues that a lot of PC players are experiencing.
