Resources - CopyResource is enabled in two new scenarios: New sample-frequency pixel shader execution with primitive rasterization.This means that some multisample rasterization from Direct3D 10 are no longer supported. MultisampleEnable only affects line rasterization (points and triangles are unaffected), and is used to choose a line drawing algorithm.Rasterization Rules - The rules for rasterization have changed for lines, in addition, new functionality has been added.

Pipeline Stage Bandwidth - Increased the amount of data that can be passed between shader stages: Resource

The PSInvocations pipeline statistic increments at sample-frequency unless the shader is running at pixel-frequency. Naturally, running at pixel-frequency always produces the same results as running the same shader at sample-frequency, when the attributes are sampled at a pixel-frequency. In that case, it is equivalent to the hardware executing the shader once per pixel (pixel-frequency), replicating the result to all covered samples. If a pixel shader doesn't use any per-sample attributes, then it will compute the same value for each covered sample in a pixel. To achieve this, all multisample semantics are defined as if the pixel shader always runs once per sample (sample-frequency), computing a separate color per sample. Multisample Anti-Aliasing - Multisampling has been enhanced to generalize coverage based transparency and make multisampling work more effectively with multi-pass rendering. Blending is also required for UNORM16/SNORM16/SNORM8 formats. (accuracy to 0.5 ULP for multiply, 1.0 ULP for reciprocal).įormats - The precision of float16 blending has increased to 0.5 ULP.

This applies to addition, subtraction, and multiplication. Dual source blending operations are restricted to render target slot 0 you may not write to other outputs or have any render targets bound to slots other than slot 0.Ĭulling Behavior - Zero-area faces are automatically culled this affects wireframe rendering only.įloating Point Rules - Uses the same IEEE-754 rules for floating-point EXCEPT 32-bit floating point operations have been tightened to produce a result within 0.5 unit-last-place (0.5 ULP) of the infinitely precise result. Direct3D 10.1 extends the feature set of Direct3D 10.0 with the following new features:īlend Modes - Independent blend modes per render target using the new blend-state interface (see ID3D10BlendState1 Interface).
