So, I decided to try booting up LSW3 today, but kept getting a dim screen issue on the first level. After some online searching, I determined this was a known bug, but no one had yet found a solution. It turns out, the solution is actually really simple: in the Game's appdata folder (%appdata%/LucasArts/LegoStarWarsIII), open up 'pcconfig.txt' and scroll to the setting 'ExposureControlEnabled' and change that from a 1 to a 0, the level should now be lit like it's supposed to! Happy gaming everyone, especially lego star wars 3 players on intel graphics!
