When optimising your gaming settings, you have probably stumbled across Anti Aliasing, but what exactly is it?
When you purchase a new PC game, the first thing you normally do is double-check that your PC's specs can handle the minimum hardware requirements. For the most part, you'll be able to at least play the game with nothing extravagant, even though most modern games require some pretty darn expensive and powerful gaming PC components to play at full resolution and frame rates.
This is exactly where Anti Aliasing (AA) comes in. Computer-generated graphics are made up of millions of square pixels vertically and horizontally, this means that if you want to display information that is either a straight line vertically or horizontally, you'll have no problems at all. The issues come in when you want to display-diagonal or rounded information.
This issue is easily solved by simply having more pixels in your display to minimise the effect of this, however, this is far more expensive to the consumer. So, Anti Aliasing is the next best thing. Anti Aliasing is digital signal processing, spatial anti-aliasing is a technique for minimising the distortion artefacts known as aliasing when representing a high-resolution image at a lower resolution.
