From what I could see only SSAO & SSIL were affected when they both
call:
int zero[1] = { 0 };
RD::get_singleton()->buffer_update(ssao.importance_map_load_counter, 0,
sizeof(uint32_t), &zero, 0);
int zero[1] = { 0 };
RD::get_singleton()->buffer_update(ssil.importance_map_load_counter, 0,
sizeof(uint32_t), &zero, 0);
Also documented what setup_command_buffer & draw_command_buffer are for.
