Slow System Response with Windows 7* and SM712 On Board Video Driver

You may notice the system responds slowly after installing an on-board video driver in Windows 7*.

• When moving the mouse or opening a new window, there may be a delay of 2 or 3 seconds
• New windows may open slowly, or haltingly

Affected products:

• Intel® Server Board S1200BTS
• Intel® Server Board S3420GPV
• Intel® Server System R1304BTSSFAN and P4304BTSSFCN

What is the cause?
The Intel boards and systems affected use an on-board SM712 video chip. The SM712 is a 2D video chip and does not have 3D acceleration capability. This forces Windows 7* to use the CPU to draw window rectangles and video. 

How to fix it:
To resolve this, disable the hardware acceleration on the system:

1. Right-click the desktop and choose Screen resolution
2. In the Screen resolution window, click Advanced settings
3. In the Generic PnP Monitor and Silicon motion LynxEM+ properties pop-up window, click Troubleshoot tab
4. Click Change settings
5. Set Hardware acceleration to None and click OK
