After updating to 0.1.6 I have frame drops when I zoom in on the railings of the raised rails.
The fence probably has some issues, after I went back to 0.1.4 it went away.

What kind of graphics card do you have and how much vram does it have?

On my 4070 Ti Super its all good, but im playing with 2 guys with RX 580 with 8 gig of Vram.
They're having problems keeping up. Their fps drops to around 15 to 20.

With my update I have added a lot of textures which increase the vram requirement significantly. If you are currently using all my mods, the vram requirement increases by an additional 8.2GB to the base game. I assume that the 8GB graphics cards of your friends are at the limit.

Currently my PC with Factorio (with mods), browser window with a stream, Steam, Discord etc. uses 14GB of vram.

Due to your request I have updated the information in my modpackage, you might want to take a look.
