Changes of the current version::

  • Improved detection of GeForce 9 cards

Last aTuner news:

  • This is one of the last aTuner updates.

Known Problems:

  • After fresh driver's installation: It can happens, that the options are "jumping back". If this occurr, apply the "Default"-Button, end aTuner and start it again. If the problem persists, go to the driver's control panel and set the options to any user-defined setting, and check if aTuner now works properly.
  • nView or Windows Dual-Monitoring: aTuner should be closed by the user, before another screen is activated or deactivated. Since Forceware, you can try to just rightclick on the aTuner monitor-buttons ("P", "S") and a menu will appear. With this menu you can force aTuner to detect the new monitor configuration without an explicit close and restart of the tool.
  • Zoomed Fonts: All current aTuner-versions offer a workaround. Please look in the aTuner-folder for the "zoom.txt"-file.
