The easiest thing you can do on Wine is run using WINEDEBUG=+fps :)
(assuming the game uses double buffering which all modern games do)

There are also other ways but I'm not sure if they work with Wine at
this point. Basically tools like Fraps inject themselves into the
Direct3D/OpenGL call which is responsible for showing a new frame. In
case of Linux apps the best you can do is hook into glXSwapBuffers but
Wine loads opengl at run-time, so that doesn't work. The +fps channel
calculates the framerate around that call in the Wine code.

If you want to more detailed measurements also try to use WineD3D on
Windows. It could give you an indication how big the impact of the
drivers is and perhaps Wine is. If you are using Nvidia the OpenGL
drivers should be the same (perhaps there would be a difference of a
few percent but you could ignore that), so in that case the
performance we are losing is due to Wine/Linux.
