Hey,

comment/uncomment 26 line to see difference between cpu and gpu particles. i expect this is not correct behaviour. the problem that i can’t create proper particle type based on user’s browser’s particle support. With current behaviour i need to write separate code for cpu and gpu particles which i expect is not correct.

Could you please check?

Nice catch!
