Static Samplers Define sampler parameters right in the root signature – Or right in the shader <strong>with</strong> HLSL root signature language No performance advantage on Haswell/Broadwell – Driver places static samplers in the regular sampler heap – Same as manually putting them there manually Use them if they are convenient – Performance should never be worse Copyright © 2015, Intel Corporation.
