Xtasy X850XT 256MB Pcie SMOOTHVISION HD is a set of technologies designed to enhance the image quality of any game using advanced, high-performance filtering technology. Anti-aliasing removes the distracting jagged edges that can occur on the outlines of 3D objects, and Anisotropic Filtering sharpens blurry textures and retains the fine details in the image. 3Dc is an exciting new compression technology designed to bring out fine details in games while minimizing memory usage. It is the first compression technique optimized to work with normal maps, which allow fine per-pixel control over how light reflects from a textured surface. With up to 4 - 1 compression possible, this means game designers can now include up to 4x the detail without changing the amount of graphics memory required and without impacting performance. HYPER Z HD is an essential technology for unlocking the potential of High Definition Gaming in the RADEON X800. By maximizing the efficiency of data transfer between graphics memory and the 3D rendering engine, it removes the key memory bandwidth performance bottlenecks that otherwise occur when rendering complex, anti-aliased scenes at high display resolutions. This is accomplished through a combination of hidden surface removal, lossless compression, caching, and fast clearing techniques.Min Intel Pentium 4, AMD Athlon K8 with PCI-Express X16 Slot 128MB of system memory
