Usage of cores

The problem is that multi-threading game such as GTA IV uses only one core on
dual core system. I uploaded cores usage during the play to show the problem.
The game should use all cores that are in system.

Typing  
taskset -p PID_OF_GTA4
in terminal when GTA 4 runs shows:

pid PID_OF_GTA4 current affinity mask: 1

Changing affinity mask to 2 doesn't change usage of second core.

Additional information:
CPU: Intel Core 2 Duo
OS: Fedora 12 32 bit
Wine: 1.1.40+TEXP70 from bug #16328
GTA4: English version patched to 1.0.5.0
