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.
