Insane stuttering 64bit client

  • After today patch, when playing Diablo 3 on 64 bit client, i am having insane stuttering, while the 32bit client works fine.

    I've checked in with Customer Support, and they suggested me to post in here, since they seen my drivers were up to date, even scan and repair did not help, as there were no issues with it and no files were downloaded.

    This is the first time i have this issue since i've always used 64Bit client until now.

  • We are currently investigating the cause of the stuttering. In the meantime, some players have reported that setting Diablo III back to 32-bit has helped out.
