This lab exercises the error and performance checking capabilities of the Web Driver. When the driver is initialized by placing it on a web page, errors encountered during initialization can be retrieved using the WT::getInitStatus() method. This method indicates critical errors if DirectX is not installed, or if an unsupported color depth (such as 256 colors) is set. If a critical error ocurrs during initialization, then all methods but getInitStatus will return errors. The lack of hardware acceleration is a warning, rather than an error, and will not interfere with driver initialization. You can, however, use this warning to notify the user that they may experience poor performance.
Once the driver has been initialized, the WT::getPerformanceInfo() method is available. The information returned by this method can be used to further refine and scale your content to match the user's hardware.
