This article was originally posted on our website as a guest blog post in June 2014. The post was revised in February 2015 to include an updated version for our 2015 update. The article was originally titled “Dynamic Range” and is now titled “Dynamic Range Compression for Gaming”.
Dynamic range compression (DRaC) is a technology that makes the level of detail present on an image or video smoother. It’s used on almost every piece of video game hardware and is an essential part of modern gaming. In the case of video game graphics, it’s a particularly important technique because of the way that computer monitors work. The resolution of a monitor is just one of the factors that makes a video game look smoother.
DRaC makes a video game look smoother because it reduces or eliminates the flicker and/or jitter. It also makes a game run faster because less time is required to render each pixel in the image. The technique takes the same amount of processing power as it did before, but it uses less memory.
A good gaming video game will have a small peak and a much smaller valley, the small peak being called a “dynamic range”. It is the difference between the color of a piece of video game graphics that is not perfect and the color of a game that is perfect; for example, in a game with perfect colors, the color of a character’s skin is the only thing that has a value.
This technique is used in gaming for a variety of reasons, but primarily it serves as the difference between “dynamic” and “stiff” in a video game. Dynamic range is the range of colors that a piece of video game graphics can take before it becomes impossible to render properly. The range of colors that is allowed to drop to 0 is called the dynamic range. In a game with no flaws, the game’s dynamic range is 0.
