You will need
  • - computer
  • - drivers for video and audio Board
Hardware acceleration at the moment requires a lot of applications that work with video and sound. If acceleration is not set, the system can receive the failures, as to the processor imposed great challenges.

The function is increasing or decreasing hardware acceleration becomes available only after installing the device drivers. The necessary drivers are included with the device (CD-ROM). If you have these discs were not available, then the drivers can be downloaded from the official website of the manufacturer of your hardware.

You will also need to install Direct X, which is freely distributed in the network. It is worth noting that almost every game drive includes Direct X.
