For the best performance when using Adobe Flash Player from your browser, you should close all other windows and tabs and quit any applications that are consuming network bandwidth. If Flash continues to perform poorly even when your PC is consuming minimal resources, you may need to update or reinstall certain software, such as your graphics driver, or turn on Hardware Acceleration, a feature of Flash Player that uses your video card to improve the quality of playback.
Enable Hardware Acceleration
Navigate to the video you want to watch and then right-click the media player.
Video of the Day
Select "Settings" from the context menu to open Adobe Flash Player Settings and then click the "Display" tab.
Check "Enable Hardware Acceleration," click "Close" and then restart the browser.
Update or Reinstall Flash Player
Browse to the Adobe website (link in Resources) and then check under Version Information to see which version of Flash Player is installed to your system.
Find your browser in the table on the bottom of the page and then check the adjacent cell to see the latest version for your software.
Download and install the update (link in Resources) to your browser, if applicable. If your browser is already up-to-date, download the uninstaller for Flash Player (link in Resources).
Close your browser and launch the uninstaller. Follow the on-screen prompts to remove the software from your computer.
Restart your computer when the process completes and then launch your browser. Download and then reinstall Flash Player.
Update Your Graphics Driver
Press "Windows-X" from the desktop to open the Start menu and then select "Control Panel" from the options.
Select "Small Icons" from the "View By" drop-down menu in the top right and then choose "Device Manager" from the list of modules.
Double-click "Display Adapters" and then right-click your graphics card.
Select "Update Driver Software" from the context menu and then click "Search Automatically for Updated Driver Software."
Follow the on-screen prompts to install the update to your graphics card if Windows locates a new driver for your system.
In rare cases, hardware acceleration may reduce, not boost, performance. If hardware acceleration is already enabled, disable it and then restart your browser to see if playback improves.
Flash Player is integrated into Google Chrome, so you do not need to manually update or install the plug-in. If, however, you've installed Flash Player to your computer to use with another browser, like Firefox or IE, the installed version may conflict with the integrated plug-in. Browse to "chrome://plugins", click "Details" in the top right and then click "Enable" beneath Pepflashplayer.dll or NPSWF32_13_0_0_214.dll.
Certain third-party software, such as endpoint security software, may conflict with Flash Player. Contact the vendor if you have any difficulty configuring your software, as settings vary across products.
