ATI Technologies Z1-128p, X1-256P specifications Force copy swap, Wait for vertical retrace

38 Using Your FireGL Card

If you add or modify a configuration profile, select or clear the checkboxes in the Settings section according to your requirements.

Default Settings

Enable 8-Bit double-buffered Overlay Planes

Use 8 bits of each 32-bit frame buffer pixel as double-buffered overlay planes.

Force copy swap

Force blit copy during double-buffer swap from back to front buffer.

Wait for vertical retrace

Buffer swap 'synched' to the refresh rate of the monitor. Enabling will lower the frame rate but reduce visual artifacts such as tearing. Disabling allows your application to run at the highest possible frame rate, regardless of the monitor’s refresh rate, which is typically less than the frame rate at which the application will run.

Enable OpenGL Hardware acceleration

Always enable this setting for hardware acceleration of your OpenGL application. Disable this setting only if you experience serious rendering problems. Disabling this setting significantly reduces the OpenGL performance.
