What are your system specs?
My laptop (i5 2520M, HD 3000, SSD) loads nhelens in 4s and Auriga in 2s.
I'm using Xubuntu 14.04 with OpenGL.
This is with all gfx set to minimum though. Shader effects etc. slightly affect loading performance but I don't notice any real difference when maximizing everything.

I copied your settings and nhelens still loads in 4s. Could you set everything to minimum to see if it makes a difference?

No difference with minimum settings.

It would be great to get some more input from other users, ideally with GPUs from Nvidia, Intel and AMD to see if it's vendor specific.

nVidia GeForce 9600 GT (Wineskin)
North St Helens
-openGL: 14s
-DirectX 9: 14s
It takes a long time probably because my HDD has only ~20 gigs free and/or my computer is 6 years old.
It loads a lot slower than older versions though, probably because of the new real-time shading (right?).

i5 4570, SSD, Nvidia GTX 760, Windows 8.1
nhelens:

  • OpenGL: 4s
  • Direct3D9: 4s

Maybe it's AMD specific?

On Windows 10 x64 even little bit worse.
Auriga : 2s vs 7s
Brutal Valley: 6s vs 8s
North St Helens: 4s vs 22s
North St Helens Suspended Monorail System: 5 s vs 43 s

I can now oberve this with Auriga on i7 6700, SSD, Nvidia GTX 760, Xubuntu 15.10

"saving terrain pages" takes forever now.

I think this is related to the generation of the terrain cache (*.mapbin), since #566 all maps load very fast on Linux with OpenGL.

So we disable the .mapbins all together, at least when OpenGL is used?
