What was not tested
Multiplayer

Additional Comments

I had to purge pulseaudio, apparently it can't handle something and causes a buffer underun which is what has been cutting out sound for me.  

I also installed everything through official sources then I had to use one of the older RELOADED cracks so I didn't get the securom error.

As for anything else, it seems to run pretty decent without any modifications.
