Catalyst™ Control Center
ATI’s all-new Catalyst Control Center goes far beyond traditional driver configuration software—it’s a feature-rich and stable 3D acceleration control application that puts you in complete command of your ATI visual processing unit (VPU). Catalyst Control Center offers exceptional graphics performance and visual quality for the ultimate in performance, stability, and innovation. Safe GPU overclocking, custom profiles, and assignable hotkeys are just a few of the many new features. You’ll also enjoy frequent updates, reliable customer service, and an interactive user feedback program, all backed by ATI’s technical confidence, industry-leading capability, and uncompromising commitment to creating your ultimate visual experience.
Microsoft® DirectX® 11
The power of DirectX® 11 with awesome performance, stunning visual effects, and more dynamic interactivity than ever before.Ensures the best performance and application compatibility for all DirectX® 11 applications. Microsoft® DirectX® 11 games, with stunning 3D graphics and shading effects.
Shader Model 5.0
Shader Model 5.0 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 hardware’s ability to hide latencies.
OpenGL 3.1® Optimizations
Ensure top-notch compatibility and performance for all OpenGL 3.1 application.
