Das kommt auf die Effekte an und wie oft sie verwendet werden. Aber DX12.1 ist schon eine interessante Erweiterung:
12.1 a) Conservative Rasterization:
Conservative rasterization means that all pixels that are at least partially covered by a rendered primitive are rasterized, which means that the pixel shader is invoked. Normal behavior is sampling, which is not used if conservative rasterization is enabled.
12.1 b) Rasterizer Ordered Views:
Standard graphics pipelines may have trouble correctly compositing together multiple textures that contain transparency. Objects such as wire fences, smoke, fire, vegetation, and colored glass use transparency to get the desired effect. Problems arise when multiple textures that contain transparency are in line with each other (smoke in front of a fence in front of a glass building containing vegetation, as an example). Rasterizer ordered views (ROVs) enable the underlying OIT algorithms to use features of the hardware to try to resolve the transparency order correctly. Transparency is handled by the pixel shader.
