SYMPTOMS
QueryPerformanceFrequency() called from an application running on an NEC
PC9800 Series computer with Japanese Win95 (PC9800 version), returns a
static value (1193180 Ticks/sec) regardless of the actual frequency of the
high-resolution performance counter. On NEC PC 9800 Series computers, the
static value can be 2457600 ticks/sec.
RESOLUTION
The same API returns the correct value on NEC PC9800 Series computers
running Windows NT PC 9800 version.
This problem does not exist on any other platforms.
STATUS
Microsoft has confirmed this to be a bug in the Microsoft products listed
at the beginning of this article.
This problem was corrected in Windows 2000.
