Guru3D has discovered that Ubisoft has taken it to a whole new ballpark. Whilst trying to install the game Anno 2070 on three different computers (for review purposes), they discovered something. One of the computers was an NVIDIA Graphics Test PC. They took out a GTX 580 graphics card and inserted a GTX 590. Now here's where their troubles begin.
Instead of monitoring the number of PC's that you are using, Ubisoft also monitor your hardware itself. Meaning, that, once the user switched graphics cards, the activation key was no longer valid and the game wouldn't work anymore.
Best part is if they wanted to review the game, they'd have to buy the game seven times. Ubisoft's response? Tough luck.
In short, Ubisoft DRM doesn't just track the computers, but it also tracks your hardware. Meaning, switch one thing out and lose an activation code. Better be careful in the future, you could get screwed over worse than you could ever imagine.
Does Ubisoft hate their customers or something?
