Yay more ATi confusion, not all R520 chips are produced the same. More great news for hardware enthusiasts, upgrade to Vista or use HDCP and you'll need to upgrade your hardware. Not all is happy in the Battlefield 2 post 1.03 patch days. While I haven't experienced any problems, this certainly sucks to hear.

Thanks to a couple of responses from readers this morning we've found a distinct problem with the latest patch for Battlefield 2. It looks like the 1.03 patch encrypts the CD-key value in the windows registry. Most likely this is done to avoid the theft of CD-keys by malicious software while you're playing online. It's a clever move.

Unfortunately, it looks like this encryption of the CD-key is specific to the Windows User Account that was used to install the patch. If any other Windows user attempts to play the game on the same machine they are given a message saying the key is invalid.
