Summary: City of Heroes fails to detect Nvidia driver version
           Product: Wine
           Version: 1.1.32
          Platform: PC-x86-64
        OS/Version: Linux

         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Run City of Heroes on a system with an Nvidia graphics card.  The console
output will contain the following:

Driver is old because NVIDIA version < 5216
CPU: 2394 Mhz / Memory: 2047 MBs / Video Card: Unknown / Video Driver DLL:
UnknownVendor / Driver Version: UnknownVendor / Available Memory: 2047 MBs / OS
Version: 5.1.2600 / Video Memory: Unknown

On the login screen, the game will complain about the Nvidia graphics drivers
being too old.  This occurs with both the 180.60 and 190.42 drivers.

Wine does not report real driver version to the app.

More information:

City of Heroes determines the video driver version by inspecting the driver
.dll (for the current Nvidia drivers, this would be nv4_disp.dll in the
Windows\System32 directory).  It finds this file by inspecting the registry key
HKLM\HARDWARE\DEVICEMAP\VIDEO for a string value named \Device\Video0.  It then
uses that value (on my system,
"\Registry\Machine\System\CurrentControlSet\Control\Video{09848A9D-1AF4-42ED-9713-D4EFC8707D6E}\0000")
as the path to a REG_MULTISZ value named "InstalledDisplayDrivers" that
specifies the driver file without extension.

Providing a nv4_disp.dll file and the related registry entries eliminates the
"driver version" warnings.

This is unfixable. Applications should use functions from DX/OpenGL to query
information they need.
