Graphics


Parallel processing technology support

Parallel processing technology is the simultaneous use of more than one CPU or processor core to execute a program or multiple computational threads. Ideally, parallel processing makes programs run faster because there are more engines (CPUs or Cores) running it. In practice, it is often difficult to divide a program in such a way that separate CPUs or cores can execute different portions without interfering with each other. Most computers have just one CPU, but some models have several, and multi-core processor chips are becoming the norm. There are even computers with thousands of CPUs.

Not supported


Maximum resolution

The maximum number of pixels that can be displayed in the image. It is usually quoted as width - height,: for example, "1024 - 768" means the width is 1024 pixels and the height is 768 pixels.
