Summary: Warcraft III (Frozen Throne) performance issue (cpu at
                    100% all time)
           Product: Wine
           Version: 1.1.31
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

When starting Warcraft III - Frozen Throne using this command:
env WINEPREFIX="/mnt/musik/.wine" WINEDEBUG=-all wine explorer
/desktop=0,1680x1050 /mnt/disk/Programme/Warcraft\ III/Frozen\ Throne.exe
-opengl

but also without the parameters, or starting Warcraft III Reign Of Chaos using
wine /mnt/disk/Programme/Warcraft\ III/Warcraft\ III.exe

leads to one of my two CPU's being constantly at 100%, whilst the other isn't
used by wine at all.

I run a multithread test program, which showed me that multithreading in wine
works. Also I always use current nVidia graphics drivers. I had this problem a
long time already, but since the game is playable most of the time I didn't
care to report this.

I'm running Gentoo 32bit on a Nexoc E619 with a nVidia GF 8600M GT and a Intel
DualCore T7300, 2GHz.

The annoying thing about the problem is, that if you get some background
application spiking to 100% on the other CPU, the game will lag immensly.
