For reference, I'm running Ubuntu 14.04 64-bit with Wine 1.6.2. On the hardware side, I have a AMD Athlon II X4 620 processor, 8GB DDR3 RAM, a 128GB SanDisk SSD and a AMD Radeon HD 7750 GPU. I'm using the open source GPU drivers rather than Catalyst so the HD7750 is very much under utilised.

Or... as fine as the open source driver can make it. The game experiences frame stutter from time to time. Scenes with a lot of things happening at once will be a challenge to play. That means battles will be quite frustrating. I've played the early parts of the game with no issues except for the occasional lag.
Since Undying isn't a frag fest, it should be mostly playable. If you use Catalyst, the lag will probably disappear altogether. An old game like this can't possibly stress a modern GPU.
