Automatically adjust visual experience based on client performance

Specifies whether Atmel Studio sets the adjustment to the visual experience automatically or you set the adjustment explicitly. This adjustment may change the display of colors from gradients to flat colors, or it may restrict the use of animations in menus or pop up windows.

Enable rich client experience

Enables the full visual experience of Atmel Studio, including gradients and animations. Clear this option when using Remote Desktop connections or older graphics adapters, because these features may have poor performance in those cases. This option is available only when you clear the Automatically adjust visual experience based on client option.

Use hardware graphics acceleration if available

Uses hardware graphics acceleration if it is available, rather than software acceleration.

Show status bar

Displays the status bar. The status bar is located at the bottom of the IDE window and displays information about the progress of ongoing operations.

Close button affects active tool window only

Specifies that when the Close button is clicked, only the tool window that has focus is closed and not all of the tool windows in the docked set. By default, this option is selected.

Auto Hide button affects active tool window only

Specifies that when the Auto Hide button is clicked, only the tool window that has focus is hidden automatically and not all of the tool windows in the docked set. By default, this option is not selected.

Restore File Associations

Registers file types that are typically associated with Atmel Studio. Registration causes Windows to display the correct icons in Windows Explorer, and to recognize Atmel Studio as the correct application for opening these file types.

This option can be useful if you have two different versions of Atmel Studio installed on the same computer, and you later uninstall one of the versions. After uninstalling, the icons for Atmel Studio files no longer appear in Windows Explorer. In addition, Windows no longer recognizes Atmel Studio as the default application for editing these files. This option restores those associations.
