Hi
i don't really know if it is a bug, but at least it is a problem with teamspeak for many users.
If you setup your machine to disable the display device after xx minutes of idle time, the AMD Graphics Core Next cards enter a 'zerocore' mode.
In this Mode the Fan stops spinning and the card needs less energy.
BUT, when Teamspeak is running in the background, teamspeak will wake the graphic card every 2-3 seconds. As a result, the graphics card switches to 2D mode for a very short time and turns on the fan. It's just for half a second i think, but it is very annoying to hear the fan start spinning every 2 seconds.
In the attachment there are 2 pictures with graphs from MSI Afterburner.
The first shows the behaviour of the card when teamspeak is running in the background while system is in sleep and the second shows when teamspeak is not open.
i hope you can understand the problem
please note that teamspeak3 does not wake the system at all, it just prevents the graphics card entering the zerocore mode!
