Shader Model 3.0 Windows 10 What Is Shader Model 3.0 Chipset models in the series (excluding RD690 and RX690) feature an Integrated Graphics Processor (IGP). Ps.3.0 – Early Outs Early out is when you do a dynamic branch in the shader to reduce computation Some obvious examples: If in shadow, don’t do lighting computations If out of range (attenuation zero), don’t light Obviously these apply to vs.3.0 as well Next – a novel example for soft shadows. Depending on resolution, in excess of 2 million pixels may need to be rendered, lit, shaded, and colored for each frame, at 60 frames per second. A Pixel Shader is a graphics function that calculates effects on a per-pixel basis. The PS 3.0 shader model is more sophisticated than PS 2.0, which allows for even more effects on supported hardware.' - from What's New in WPF Version 4 But in WPF 4.5 or 4.6, WPF didn't change the s upport capacity for Pixel Shader.
