Great news! The first patch for The Witcher 2: Assassins of Kings is available right now in the "additional content" area of your download in "My Account" This patch fixes a number of issues. From the patch notes:

1. Fixed the free Troll Trouble DLC download. It is now included in the patch so there's no need to download and install it separately.

2. Fixed an issue that prevented some users from downloading other free DLCs (the ones given out with some pre-orders, special promotions, etc). The launcher now properly refreshes the list of available DLCs and allows for installation.

3. Performance improvements: approximately 5% to 30% better framerate and faster game loading for many users, depending on their individual systems and game versions. Owners of retail versions can expect the biggest improvements.

4. Fixed random crashes occurring on some systems, especially after saving and loading saves.

5. Key mapping – allows the arrow keys to be used for movement.

6. Added the option to invert the mouse.

7. nVidia surround vision now works properly.

8. More accurate assessment provided by the "auto-detect settings" option will help improve game performance.

9. Removed a bug that prevented completion of the “Blood Curse” quest.

10. GOG.com credits now work properly.

The last bugfix, of course, was the most important one, since you can now see who worked so hard at GOG.com to bring you the best digital version of the game anywhere on the 'Net!

As always, you can head over the The Witcher's website or let us know in our forums if you're experiencing problems.

Note: This patch only works on the gog.com version of the game.
