For troubleshooting information, see Troubleshooting Device.Graphics Testing.Turn off the screen saver and disable the power management before you run this test. Mode changes and full-screen applications can cause failures, so you should avoid them.

More information

Most of the Microsoft DirectDraw tests (including the Blt - Exotic test) are located in Fnddraw.exe. You can run Fnddraw.exe outside of the DCT shell, and select initial tests. On the Tests menu, click Select Tests.

The test titles that are listed in the DCT shell do not directly match the test names in Fnddraw.exe. In fact, the names in the DCT often refer to a group of Fnddraw tests. You can obtain the Fnddraw test case names from the DCT log file.

You can pause many Fnddraw tests (especially blt-related tests) to give you time to visually analyze the blt results. Use the <Pause> key to pause and resume.

Use the <ESC> key to abort a test run. Be patient because some tests are more responsive than others.

Command Syntax
