Bitdefender Causing Dpc Latency

Options

in General

The DPC latency issue makes my CPU spike which stutters my whole computer (audio stutters, laggy mouse movements, freezing programs) http://puu.sh/oS70i/84f8a12613.png


I uninstalled Bitdefender and it reduced my DPC Latency by a lot as seen here http://puu.sh/p6TlJ/7cab43c65a.png

I'm using drivers from Mediatek and last update was Nov 3rd 2015 and it's the only Win10 drivers they have

http://www.mediatek.com/en/downloads1/downloads/


Is the driver conflicting with Bitdefender, or vice versa ?

I don't have any other AV / AM installed, it might be the firewall causing it cause of this thread

    I had the same issue and turning off port scan detection solved it for me.

    It's in 'Module' > 'Firewall' > 'Block port scans in the network'.

    I hope this helps and that they can fix this asap.

    That actually seems to fix the problem

    So I turned off the "Block Port Scanning" and that fixed it, will there be an update to fix it ?
