Does anyone know if this patch solves the PunkBuster issues with OnBoard Audio Drivers?
Doubt it, the fixes are all listed,
Removed some memory leaks
Fixed crashes when the game attempted to render lots of content (high detail, high FOV or multiple-monitor modes); this should particularly help multi-monitor users
Chat window no longer causes lag spikes
Chat window reworked opacity & visibility-time is controllable through settings in settings.ini
Clantag is remembered when using auto-login
Banner URLs can be up to 252 characters in length
SecuROM wrapper removed from non-Steam version
Minor performance enhancements
Reduced rubberbanding on servers with more than 24 active players
