Game persistently becomes non responsive after updates as of 3/18/2013 in the afternoon (us est).
Windowed Launches and some times full screen launches fail repeatedly.
Multiplayer Matches often fail either during the join process or at the briefing screen, (most noteworthy being only able to log into one match to have my character disappear and then the game crash shortly after attempting to move). {F18239}
Update to the latest dev release.
Maybe have similar hardware
I do Overclock however turning that off doesn't seem to have an effect.
Have had to deal with a zombie window IE window can't be closed and task manager reports a permission error when attempting to forcibly halt the process
Was able to play up until this point at about 30fps with minimal performance glitches although accompanied by infrequent game crashes. (frame rate measured with rivia tuner)
