A vast or significant amount of the 100+ hours I’ve spent playing Skyrim so far has been tweaking the game back and forth between playable and beautiful, often shifting many times every day. While messing with uGrids in the Gamebryo Engine can destroy save files and create massive instabilities within the game it offers some of the better enhancements to visual quality and is the actual limiter for many standard tweaks. uGrids are literally the game world itself, how much the of the game world the engine will actually render and calculate at any given time, broken up into ‘grids’ around the player with the default being 5 and playable being 7, though more adventurous users going for great still images opt for 13+ uGrid for what I can imagine is not so much a game but rather a crash fest.
