For some reason the game usually crashes the first time I open it, and then it's fine after that.
Performance is all over the place if you mess with the settings though. I'll be getting close to constant 60fps, tinker with a few tings and then change them back, and all of a sudden I'm getting 40fps in the same area with constant stutters, regardless of whether or nor I'm in Mantle or DX11.
On the whole I get better performance with Mantle, but every few minutes when a new area is steaming in the background or something I get a sudden drop to 10fps for a second or two before it jumps back which is super annoying.
