No, I think they work with the AMD binary blob driver as well, but they have some display/compatibility issues with the drivers on those. You should check the official GIthub trackers for Witcher 2 and Bioshock Infinite, some issues are reported there.
What I find strange is that the game starts and seems to render fine, and then crashes the whole machine[1].
