What is fidelityfx cas?

FidelityFX CAS stands for FidelityFX Contrast Adaptive Sharpening, which is an advanced image sharpening technique developed by AMD. It is designed to enhance the clarity and detail in video games, especially when running at lower resolutions or with lower quality anti-aliasing.

CAS uses a combination of contrast adaptive sharpening and optional upscaling to improve the visual quality of games. It intelligently sharpens only the areas of the image that need it, without over-sharpening or introducing artifacts. This helps to maintain the overall image quality and prevent the appearance of jagged edges or blurry textures.

FidelityFX CAS is supported on a wide range of AMD GPUs and is available in various game titles, as well as being integrated into the AMD Radeon Software. It can be applied either through the game settings or via the graphics driver software.

One advantage of using FidelityFX CAS is that it can provide a performance boost in games. By using a slightly lower rendering resolution and then upscaling with CAS, the GPU workload can be reduced, resulting in improved frame rates without sacrificing too much image quality.

Overall, FidelityFX CAS is a powerful tool for improving the visual fidelity of games, particularly in situations where performance may be limited. It helps to deliver sharper, more detailed images with reduced shimmering and aliasing effects, resulting in a more immersive gaming experience.
