WOW! This is is a crazy speed-up for animated fractals!!
Are you talking about the Snap with your new Morphic or we can try and see this speed-up in the existing Snap, as well?
We should thank dardoro for identifying the problem.
this is going to be in the next major release I'm currently working on 
Can you make a video so we can watch a sped-up fractal animation, please?
absolutely, @dardoro, excellent analysis, as always with your contributions. Awesome to have folks like you watch over us. Thank you!
You're welcome ...
so now raycasters will display 8 columns instead of the usual 4?
I made a remix of Your project
It renders the entire scene with 60 degree FOV at 5 FPS (because of hard work done).
Your original project, prematurely starts "Rendering" right after begin of "Scan" phase with almost empty "Distances" list so wrong image displayed.
There is a workaround for the current Snap release.
Loop with procedure warped this way works at full speed.
There is a slightly modified version of Your project.
The screen is updated every n-th game loop iterations. For n=2 perceived performance is quite good, for 4 insane.
forever{
warp{
repeat(2){
game loop iteration
}
}
}
Sorry, project URL updated.
