@s-perron @Keenuts I'm not an expert in HLSL/GLSL, but AFAIU transformations that are added in the patch are invalid for Logical addressing. Would you like me to guard Shader (without PhysicalStorageBuffer64 capability) flow from this change or do you not expect to see `ptrtoaddr` at all at the flows you concern about?
