Hi!

I'd like to suggest to make Eleveted Rails as an "Extension" of the HD age mod. Alternativly a bit of thinkering with the mod (?)*

Apart from high VRAM usage for some reason it is extremely GPU intensive.

Straigh rails cause relativly high GPU usage but still 60 FPS
With curved rails even just a simple "Circle" makes it expensive to process for GPUs

I was able to mitigate this issue to some level by changeing Atlas texture size from "Largest possible" to 2048 (not tested the other ones) and put some extra load to my CPU. Even after this change GPU usage between a full factory and just a couple of elevated rails are enormous.

My VRAM usage 7,5 GB at 1080P

Setup
Ryzen 5800X
32 GB 3600 MHz
RX 6600 XT

Hi,

The fact that the elevated rails require so many resources also bothers me. I keep thinking about a solution, but haven't found one yet.

Since I want to provide a complete modpack, I will not remove the elevated rail dependencies.
But you can deactivate and delete the modpack and the elevated rails, then all other HD age mods remain and receive updates.

I have created a version of the mod package in which all mods are optional.
