Skype 5.0 and higher for Windows uses Microsoft DirectX, which makes use of the hardware acceleration features of modern graphics adapters. If DirectX 9.0c or higher is not installed on your computer, Skype can make use of Windows' basic graphics capabilities, but this places additional demands on your CPU, and can cause Skype to run slowly. To avoid this, and to ensure the best performance when making video calls:
•Ensure your computer meets the requirements for video calling.
•Ensure DirectX 9.0c or higher is installed on your computer.
•Update your graphics adapter drivers.
Checking if DirectX 9.0c or higher is installed on your computer
To check whether DirectX 9.0c or higher is installed on your computer:
1. Open the DirectX Diagnostic Tool.
•On Windows 7:
Click Start > Programs > Accessories > Command Prompt, type dxdiag and press Enter.
•On Windows XP & Vista
Click Start > Run, type dxdiag and press Enter.
2. Check the version of DirectX that you have installed.
On the System tab, in the System Information area, next to DirectX Version, check the version number displayed. If it is 9.0c or higher, proceed to the next step. If it is lower than 9.0c, you will need to upgrade. For Windows Vista and Windows 7, get the latest version of DirectX by updating Windows with the latest service packs and updates. For Windows XP, download it here.
If the DirectX Diagnostic Tool does not open, or an error is displayed, then it is likely that you do not have DirectX installed on your computer. Download and install it using the links above.
Remember to restart your computer after installing or updating DirectX.
3. Ensure that DirectDraw Acceleration and Direct3D Acceleration are enabled.
4. On the Display tab, in the DirectX Features area, ensure that DirectDraw Acceleration and Direct3D Acceleration are listed as "Enabled".
5. Check the Notes area at the bottom of the Display tab, and check that no problems are found.
6. Click Exit.

If you're having problems with video on a Skype call, and you've already tried the steps in the Connection Troubleshooter, there are a few things you can check to make sure your webcam is working properly.
Skype for Windows Desktop
Before proceeding with the troubleshooting steps below, first ensure that you are in a room with proper lighting (bad lighting can make your video too dark to be seen by the people you're calling.
Also, if you're using a webcam that plugs into your computer via USB, you might not be sending great video (or your webcam might not work at all) because you’re using other USB devices. An overloaded USB port can make your computer think the webcam is in use by another program, even when it's not. Try disconnecting your other USB devices, or try connecting your webcam to an alternative USB port. If your webcam is plugged into a USB hub, try plugging it directly into a USB port on your computer instead and see if that helps.
