QT4+irrlicht under windows and linux

[Kostya]

I vahe project that use irrlicht as 3d engine and qt as GUI to manipulate data in 3d scene.

I compile this project under windows and under linux.
But i found one strange thing: in linux, windows binaries running under wine (use dx9 renderer), work faster, than native linux binaries.

I don`t understand what make irrlicht so slow under linux.

And always whith qt irrlicht work slowly, but i need complex gui. in irrlicht gui too poor.

i use irrlicht 1.7.1 and qt 4.6
