This will not change the laser code, but will make it use twice as much memory as before. If you are not using many laser rays in your beams this should be ok. If you are using millions or rays, you will see performance degradation.

From your current Config file the Particles/localAPI directory is never reached and hence you don't have the compiled pt_interface.mod file.

The +laser setup shortcut contains an explicit -without-unit=Particles statement, so there can be some issues when having Particles and Grid/Particles activated at the same time.
