WillyDio: 1. First one I saw was after starting game for the 1st time, and trying to access the options for the graphics. It'll blink the graphic options then screen goes black, sound still plays, but can't do anything. Task manager states it's still running (no "not responding messages"). Have to forcefully shut the game down and restart.

For whatever reason, accessing via the game pad caused this for me, repeatedly. After 4th hang on black screen, I instead used the mouse to access the graphics options even though the game pad (360) was still connected, then it stopped hanging. Was able to use gamepad from that point further. Also, might need to close steam.exe IF it's happening or running in the background. Might be a conflict with steam's overlay and/or controller support. Unsure why steam was running. Also forced vsync in gpu settings (nvidia 3D settings panel) as they were insanely high 400+ at menu screens.

2. Opening the map sub-screen is extremely slow. Opening it at the wrong time can cause a hard game crash.

Map is always slow to open for me. I opened it during a transition and it just hung the game. My advice, be mindful of when you open the map if it's opening slow for you. Make manual saves often.
