Oh that really sucks Glad I only paid £15 for it.
My friends are using Nvidia cards and have no issues, though
That's about the size of it, hit and miss, luck of the draw I guess, only thing I can suggest is play around with your settings until you can at least get a decent fps/smoothness. Even your 290 may need to be turned down to run smoothly.
Unfortunately thats the way it is with Nvidia/GameWorks title when using an AMD gpu. Hit and miss. As AMD cannot optimize at driver level for any game using the GameWorks black box libraries you're at the mercy of Nvidia/The game Dev for AMD driver optimizations. That in itself always raises many red flags. Some GW titles work fine, but some are unplayable.
