Why are there so many loading screens in Portal 2?
Because that’s how the Source engine works. Loading screens are just as common in previous Source games, including Portal; in most of Valve’s titles, the game is paused and a small “Loading” overlay appears in the centre of the screen. In Portal 2, this has been replaced with a much more noticeable black screen featuring one of the Aperture Science logos in the middle and a progress bar in the corner. Basically, they stick out a lot more but there isn’t actually more of them. Is there a way to disable the portal funnel (being pushed towards portals as you fall), portal ghosting (HUD feature that outlines a portal when it is on the other side of a wall, etc.) and/or the game instructor (Left 4 Dead-style tooltips that appear in game telling you what buttons to press)? Yes. Behold a couple of console commands: sv_player_funnel_into_portals 0 and sv_props_funnel_into_portals 0 will disable the portal funnel for the player and physics props, respectively.
