I'm wondering why it doesn't look noisy at all for me. Only seems like the resoultion is a bit low but it looks crispy clear compared to the screenshots here ^^"

It isn't very noisy at the start! The last half of the tunnel should be much noisier. Of course, considering that the whole noisiness is a bug-turned-feature caused by the technicalities of floating-point numbers, it does depend on your hardware as well. I would be surprised if there was any hardware for which the entire tunnel is non-noisy, though.
