Enjoy powerful graphics performance improved stability and an immersive HD gaming experience for Windows Vista. ATI Catalyst software is designed for quick setup of graphics video and multiple displays and automatically configures optimal system settings for lifelike DirectX 10 gaming and the visually stunning Windows Aero user interface. By allowing the graphics processing unit (GPU) to share the capacity and bandwidth of dedicated video memory and dynamically available system memory TurboCache turbocharges performance and provides larger total graphics memory. Ensure top-notch compatibility and performance for all OpenGL 2.1 application. World\'s first DirectX 10 GPU with full Shader Model 4.0 support delivers unparalleled levels of graphics realism and film-quality effects. Shader Model 4.0 adds support for indexed temporaries which can be quite useful for certain tasks.Regular direct temporary access is preferable is most cases. One reason is that indexed temporaries are hard to optimize. The shader optimizer may not be able to identify optimizations across indexed accesses that could otherwise have been detected. Furthermore indexed temporaries tend to increase register pressure a lot. An ordinary shader that contains for instance a few dozen variables will seldom consume a few dozen temporaries in the end but is likely to be optimized down to a handful depending on what the shader does. This is because the shader optimizer can easily track all variables and reuse registers. This is typically not possible for indexed temporaries thus the register pressure of the shader may increase dramatically. This could be detrimental to performance as it reduces the hardwares ability to hide latencies.
