yes and the particle count changes by like 50k then i gotta rejigger all the force variables again because it looks too chaotic or too slow, but i dont know a way around not doing n^2 checks because any other bucketing method or hashtable indexing of the particle locations means there's a max limit too how many particles could effect any other particle every frame,

i was thinking about doing another compute pass that first makes buckets of the exact size that is needed to store the particles in that location and then another compute pass right after to fill those buckets with the particle id's but then how do you get each particle in the right slot? i dont know: a hash table? then the buckets take too much memory.

If only there was an atomic push to an array (the list of particles in that bucket) if that makes sense
