Ubi DRM activation limits respond to graphics card changes
Ubisoft's DRM isn't exactly known for its gentle, loving caress in matters near and dear to PC gamers' hearts, but the latest tightening of the cuffs seems a bit overkill-ish even by Ubi's standards. In attempting to review Anno 2070's performance on a range of hardware configurations, Guru3D made an extremely disappointing discovery: The second the site switched out a GTX 580 for a GTX 590, Anno demanded another, separate activation. On top of that, the game gives you a whopping three whole activations to work with, so think carefully before spelunking around in your machine's brittle innards.
I've fired off a mail to Ubisoft asking whether this is an intentional piece of extra armor plating for its DRM Voltron, or merely a glitch the publisher plans on patching out. Fingers crossed for the latter, though precedent's not exactly on our side.
