[Wine] Game is slower 2x than on Windows

[Mitar]

Game named Istaria: Chronicles of the Gifted (http://appdb.winehq.org/objectManager.php?sClass=application&iId=1972) ( MMO ) is slower 
on ANY linux and ANY wine version exactly 2 times .
For example on Windows I have 40 fps and in same place 20 fps on wine,
20 fps in Windows and ~10 fps on linux.
I was trying lot of "wine tricks" without any effect.
I have also installed the most up to date Nvidia drivers.
also in console wine is throwing TONS of :

Code:
fixme:d3d:state_swvp Software vertex processing not implemented.


It don't helps if I redirect stderr and stdout to /dev/null
Except low fps I have mouse problems - rotating camera using mouse is not smoothly it is sometimes slower and sometimes faster - it's "flickering".
Only becouse of this game I am forced to sit on Windows :/
I am open to any suggestions.

My hardware ( notebook ) is :
Core 2 Duo @ 2.0Ghz
4 GB DDR2
Nvidia Geforce 9300M G
