I did the update & it seems to work like a charm. My slug PC couldn't quite deal with the swarm of ships and missiles in the test scenario but during the short time I was alive it sounded great!
I don't have my 5.1 surround speakers hooked up at the moment but the difference even on headphones was amazing.
Watching the PTA turrets blast away with the new sound FX really add to the overall experience.
Thanks for the help with the patch, I appreciate it.
