This service bulletin is from HP, but it holds true with most computers featuring 'switchable' graphics.

When configuring Dynamic Switchable Graphics in the Catalyst Control Center, the notebook does not permit any OpenGL applications to be associated with the Discrete (dGPU) or high-performance GPU. OpenGL applications work using power-saving or Integrated GPU (iGPU) but performance levels are lower than expected.
OpenGL is not supported on the Discrete GPU when using the Dynamic Switchable Graphics feature. To enable discreet GPU support for OpenGL applications, enable Fixed Mode Switchable Graphics in the BIOS.

Enabling Fixed Mode Switchable Graphics in the BIOS

Enable switchable graphics mode to fixed to be able to manually choose your graphics processor setting. To do so, use the following steps:
NOTE: These steps and the screen image may be slightly different for your experience depending on the version of BIOS on your computer.
  1. With the power off, make sure the power adapter is connected to the computer and plugged into a power source.
  2. Turn on the computer using the power button and immediately press the F10 key repeatedly until a BIOS Setup utility screen appears.
  3. Press the Right Arrow key to select System Configuration .
  4. Press the Down Arrow key to select Switchable Graphics Mode .
    NOTE: If you do not see Switchable Graphics Mode in the BIOS or it cannot be selected, see the following section Updating the BIOS to enable Fixed Mode .
  5. Press Enter , select Fixed , and press Enter again.
  6. Press F10 and select Yes to save settings and exit.

Now you can set the GPU setting for high-performance or power-savings manually as needed. For more information about the Switchable Graphics feature on the notebook PC, see How to Configure ATI Mobility Radeon Switchable Graphics .

Error "No AMD graphics driver is installed" may appear after changing the BIOS setting to Dynamic Mode

If the notebook PC is using Fixed Mode Switchable Graphics and is configured to the power-saving or iGPU setting and then shutdown and changed to the Dynamic Switchable Graphics in the F10 Setup, the following error message may appear after the notebook has restarted:
No AMD graphics driver is installed
After the error appears, the display resolution will be reset to 800x600.
To prevent this issue, ensure that the notebook is using the High-Performance (dGPU) in the Catalyst Control Center before shutting down Windows and changing to Dynamic Switchable Graphics in F10 Setup.
To fix this problem after the error message appears use the following steps:
  1. Click Start , type Device Manager and click Device Manager .
  2. Click the plus sign (+) to expand the Display Adapters.
  3. Right-click the Radeon (TM) HD (AMD graphic adapter) and select Enable .
  4. Restart the computer when prompted.
After restarting, the error message will not be displayed and the display resolution will be set properly.

Updating the BIOS to enable Fixed Mode

Several series of HP notebook PCs originally came only with dynamic switchable graphics. For these computers, you must first update the BIOS to enable the Fixed mode setting in the BIOS.
The following table contains a list of products and the software needed to enable fixed mode.
NOTE:This table links to older software downloads . For the best experience, get the latest BIOS and graphics drivers from your product's software and driver download page on HP's support website.
