Huge fps drop against what? another wine version? windows? If it's another wine version you should do regression testing to give as commit that broke the performance.
I tried with same wine but nvidia 340.58 and 343.22 and problems still remains, huge performance (game appears frame by frame)
For now i still waiting next nvidia drivers beta for discard
