I haven't even gotten 10 minutes into the game. I started the game and instantly realized something was off about the camera aiming. Learned you have to turn OFF V-Sync to fix controls. Then I restarted the game with V-Sync OFF and worked much better. Then I found myself stuck at an invisible barricaded doorway. And learned that I cannot get through the door because I turned off v-sync! I guess there is a lot of research and computer savvy that you need to get the game to actually work like it should.
