EA's Tiger Woods PC golf game has an issue where the load times between holes becomes longer and longer, the more you play the game. The fix is to change the golfer files to READ ONLY, that way the file doesn't become bloated with data. Maybe try that with your season/career save, go into it and change the file to READ ONLY. You'll have to figure out which file it is first, they're only numbered, and the settings file is about 380 kb, the squad file is about 5 mb, the career file should be about 3.5 mb.
That said, cut scenes generally run slower/choppier than the game plays.
