Es gibt wieder einen neuen Teamspeak Client. Angekommen sind wir bei Version 3.1.4. Es wird das umgehende Update empfohlen.

The default OpenGL engine was changed to Angle which should help with problems that prevent the client from starting with certain graphic drivers and cards.
If the client does not start for you, try running the update.exe directly or download the setup file from the downloads page.

Full changelog below:

=== Client Release 3.1.4 13 Apr 2017
+ Angle is now the default OpenGL renderer to workaround issues with the latest
  NVidia driver update.
+ Added new commandline parameter --force-opengl-desktop, which would force the
  old default renderer
- Fixes to recently overhauled windows soundbackend
