So I had a look. The game constantly uses most of a CPU core to draw graphics
via GDI functions. In fact that's true both on Wine AND on Windows, it's just
that CPU usage is reported differently.

On Linux a 100% CPU usage e.g. in "top" means that the total CPU utilization is
one core. On Windows' task manager a 100% CPU utilization means that ALL cores
of the CPU are in use. With this game on Windows I get about 12% CPU usage,
which is essentially 100/8 (8 is the number of CPU threads I have).
