Can you explain me what parameters i have to use with valgrind ( i have installed it) so that it can makes a useful output for you?
For a start, just prepend valgrind to the final command line invoked for starting the game. I don't know offhand how to do that for XCOM, hopefully someone else can help you with that if needed.
