HKLM\SYSTEM\CurrentControlSet\Services\Mouclass\Parameters
| Data type | Range | Default value |
|---|---|---|
| REG_DWORD | 0x1 - 0xFFFFFFFF | 0x64 (100) |
Specifies the number of mouse events buffered by the mouse driver. It also is used in calculating the size of the mouse driver's internal buffer in nonpaged memory pool.
To determine the number of bytes to allocate for the buffer, the system multiplies the size of the MOUSE_INPUT_DATA structure (defined in NTDDMOU.H) by the value of MouseDataQueueSize.
You might consider increasing this value if the driver does not initialize or operate correctly and the system event log contains the following message from the source, Mouclass:
"The ring buffer that stores incoming mouse data has
overflowed (buffer size is configurable via the Registry)."
