Flash glossary: Hardware acceleration
When you specify the publish settings for SWF files in Adobe Flash Professional, you can enable the SWF file to use hardware acceleration. If the playback system does not have sufficient hardware to enable acceleration, Flash Player reverts to normal drawing mode automatically. For best performance on web pages containing multiple SWF files, enable hardware acceleration for only one of the SWF files. Hardware acceleration is not used in Test Movie mode.
When you publish your SWF file, the HTML file that embeds it contains a wmode HTML parameter. Choosing Level 1 or Level 2 hardware acceleration sets the wmode HTML parameter to direct or gpu, respectively.
Note: Turning on hardware acceleration overrides the Window Mode setting you may have chosen in the HTML tab of the Publish Settings dialog box, because it is also stored in the wmode parameter in the HTML file.
To enable the SWF file to use hardware acceleration, follow these steps:
- Select File > Publish Settings to access the Publish Settings dialog box.
- Click the Flash tab.
- At the bottom, select from one of the following options in the Hardware Acceleration menu:
- Level 1 – Direct: Direct mode improves playback performance by allowing Flash Player to draw directly on the screen instead of letting the browser do the drawing.
- Level 2 – GPU: In GPU mode, Flash Player utilizes the available computing power of the graphics card to perform video playback and compositing of layered graphics. This provides another level of performance benefit depending on the user's graphics hardware. Use this option when you expect that your target audience will have high-end graphics cards when viewing your SWF file.
