    Computer shader question

    macdonc

      I am missing something in computer shader indexing. I have a 8x8 matix which I want to write the tid into. Why does the second row below start at 0x10. I would have expected it to increase 0x0,0x8,0x10,....

      If the matrix was 16x16, I expect this output.

      "il_cs_2_0\n"
      "dcl_num_thread_per_group 64\n"
      "mov g[vaTid.x], vaTid.x\n"
      "ret_dyn\n"
      "end\n"
