Performance Issues With Voxel Game

Alright, so I have been working on a voxel game with procedurally generated terrain, each block/voxel is a model consisting of 3 cubes, these blocks have not been optimized, the only blocks that appear in the world have less then 6 neighboring blocks, I have a 48x48 world currently being rendered and it is really laggy, any help with this, preferably using visual scripting. Thanks in advance.

 

i dont know if this helps but i watched a video talking on rendering
that tells you to remember to make it static and make it many times faster.

might I ask is there are any vs videos out there covering randomly generated terrain?

 

Cycling over lots of items is slow. This is approx 2500 actions × nodes per action. Anything iterative, at this stage needs to be in code, preferably custom node while using VS as a messenger/switch/input.

Max action per frame is pushing it at 5000, bear that in mind.
