How To Evaluate Video Playback Performance While video image quality is paramount in choosing the right solution, playback performance is of equal importance. This applies especially to PCs that are set up as media centers where multi-tasking is a necessity. Here are some guidelines on how to properly measure video playback performance: Step 1: Make sure that there aren’t any unnecessary tasks running in the background. End all unnecessary tasks using Windows Task Manager.

Step 4: Once Windows’ Reliability and Performance Monitor application launches, configure it to record CPU activity for at least 120 seconds (2 minutes). You can do so by first activating the Performance Monitor window: Proceed to the Action Properties menu where you can change the duration and frequency of the CPU activity logger to the amount of time you plan to test each scene/clip in a movie: AMD believes that 120 seconds of playback is sufficient for obtaining an ac

scenes with high bit-rate to evaluate how the system will perform under heavy workload from decoding video streams. Step 5: Launch your software player of choice and make sure that hardware acceleration is enabled for each test. You can enable and disable hardware acceleration by going to the Configuration Video menu: ATI Radeon™ HD 3450 - Video Review Guide 10 ©2007 Advanced Micro Devices, Inc., AMD, The AMD arrow, Athlon, ATI, the ATI logo, Avivo, Catalyst, The Ultimat

Step 6: Start the movie and navigate to the scene that you want to use for your testing. Right before the scene begins, switch to the Reliability and Performance Monitor window (by pressing alt-tab) and start the CPU utilization logger by pressing the “unfreeze display” button or by pressing ctrl-f. Return to the movie by choosing the Cyberlink window from the task bar or by pressing alt-tab again. ATI Radeon™ HD 3450 - Video Review Guide 11 ©2007 Advanced Micro Devices, In
