In Photoshop CS6, the Free Transform command will automatically choose the best resampling method based on the transformation made. If the image is scaled up in size, then Photoshop will use Bicubic Smoother, if the image is scaled down in size, then it will use Bicubic Sharper. If for some reason you wanted to override this setting, while in Free Transform, you can change the Interpolation option using the drop down menu in the Options bar.
In addition, when dragging the transformation handles, the transformation values appear at the top right of your cursor. This display can be controlled via Preferences > Interface > Show Transformation Values (Top Right, Top Left, Bottom Right, Bottom Left or Never). Because the calculations that are taking place when using Free Transform have been moved to the GPU, there shouldn’t be any lag time when dragging the transformation handles.
The “Bicubic Automatic” option is also available when resampling an image using Image > Image Size. And of course you can still change the default option for resampling throughout Photoshop (if desired) under Preferences > General > Image Interpolation.
