UPDATE 5/28/14: Some users (myself included) have experienced issues with the official driver. It will periodically turn itself off, disabling the pen. The fix has been to either turn the pen service back on or restart the Surface Pro. Wacom engineering has corrected the issue and the new version is now available for download here: http://www.wacomeng.com/component/get.php?dlid=1507741624

The next driver update is expected at the end of June and will feature multi-point calibration and the ability to right click by tapping in the middle of the radial menu. Can't wait!

ORIGINAL POST

Wacom has just released its new Enhanced Tablet PC driver (also known as Feel IT) for penabled devices like the Surface Pro. The company last updated the driver (version 7.1.2-9) in October. That version had some calibration issues for existing hardware and was incompatible with the Asus Vivotab Note 8 released earlier this year.

The new driver, labeled 7.2.0-4 fixes the AVTN8 issue, and offers some significant additions: a new combined control panel for pen and touch sensors, a single level Radial Menu, an option in the control panel to remove the ripple effect for the pen and a couple of other enhanced features and stability improvements.

The Radial Menu is especially noteworthy as it can be customized with often-used commands and reduce the need for a keyboard with many graphics applications.

Unfortunately, calibration is still limited to four points, but in my tests on a Surface Pro, AVTN8 and Thinkpad Yoga, the calibration seems much more accurate and spots that were previously not accessible by pen (especially along the bottom of the screen where it was difficult to access the hidden taskbar) can now be reached easily.

This is especially good news for AVTN8 users who could not use their pens with software that required Wintab support because the old version inverted x, y values.
