Shader error on load

[Steve]

Just purchased the game and installed on my MacBook Pro running Windows 10. Unfortunately when I try to launch the game I get this error:

Shader: Frustum Static Compute Shader (natives/compute-static-frustum.glsl [default])

The error dialog says to confirm the latest graphics drivers are installed (checked, and up to date) as well as verify the system meets the minimum requirements. Now, my graphics card certainly isn't up to spec, but it is running OpenGL 4.4 and my typical experience with games on this machine is just having to set graphics settings really low to make them playable (not great, but I'm used to it). Strangest part is I also installed the game on my MacBook Air, which has a slightly lower quality graphics card, and the game opens just fine!

I'm also aware that my processor is slightly below minimum too, but again the Air that it's running fine is a lot worse (1.8 GHz). So although it opens the game on that machine, it probably won't be happy once I get more than a few townsfolk and buildings in the game.

My MacBook Pro's specs:
Intel Iris 6100, 1 GB - Driver v20.19.15.5144
OpenGL v4.4.0
Intel i5 2.9 GHz Dual Core
16 GB RAM
Running Windows 10 through Bootcamp

I don't really know how exactly Bootcamp is implemented in MacOS but I can see that the Intel Iris 6100 supports openGL 2.1 in OSx while 4.4 only in Windows so it could be the Mac is only downloading the version with the 2.1 support.

Another possibility I can think of is that 1GB of GRAM is probably not enough to load/render the graphics in Foundation and thus the game is unable to start.

What are the specs of the Macbook Air? Would be interesting to see the difference, maybe we can then figure out with more certainty what the problem might be.

That's good to know that Mac only supports up to OpenGL 2.1. Although, since Bootcamp allows you to boot directly to Windows (as opposed to running a virtual machine within MacOS) I'm hoping that the OpenGL Viewer wasn't lying when it said Windows had v4.4 installed.

I've managed to get a couple hours of play in with the Air, and so far no hiccups. So fingers crossed I can enjoy the game on this machine.

MacBook Air specs:
Intel HD Graphics 6000, 1 GB
Intel i5 1.8 GHz Dual Core
8 GB RAM
