I think its actually moved down the screen, in the beta it was at about the middle of the far right hand side, now its down near the bottom. Doesn't seem to be part of the hud overlay considering where it was previously.
when the beta was working I didnt have this, others mentioned it but no matter what res or image quality I set I never once saw this dot. but now the beta dont work no more and games not out on steam yet so I cant check the game yet
