 /*! \brief Allow disabling CUDA textures using the GMX_DISABLE_CUDA_TEXTURES macro.
  *
- *  Only texture objects supported, disable textures for <= CC 2.0 (but not in host code).
+ *  Only texture objects supported.
  *  Disable texture support missing in clang (all versions up to <=5.0-dev as of writing).
  *
  *  This option will not influence functionality. All features using textures ought
  *  to have fallback for texture-less reads (direct/LDG loads), all new code needs
  *  to provide fallback code.
