		Microsoft^® DirectX^® 10.1 The power of DirectX^® 10.1 with awesome performance, stunning visual effects, and more dynamic interactivity than ever before.Ensures the best performance and application compatibility for all DirectX^® 10.1 applications. Microsoft^® DirectX^® 10.1 games, with stunning 3D graphics and shading effects.

		Shader Model 4.1 Shader Model 4.1 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 3.0^® Optimizations Ensure top-notch compatibility and performance for all OpenGL 3.0 application.
