[0.16.51][mac] Crash on start: "GL_INVALID_FRAMEBUFFER_OPERATION"

[kwisatz]

Hi,

I play on my brand new MacBook Pro 2018 [edit: with Mac OS High Sierra] with core i9 and two graphic adapters :
- integrated Intel UHD Graphics 630 1536 Mo ;
- discrete Radeon Pro 560X 4096 Mo.

The game refuses to use high sprite resolution (it says more than 3Gb video ram needed, and claims that I have 1536Mb.

From the log file :

1536Mb is the integrated card memory size, when the game appears to use the discrete adapter with 4096Mb.

In the activity monitor, factorio seems to run on the discrete card indeed.

Would there be a wrong detection of video ram when there is a discrete card ?

Just in case someone would ask if the dual display is the culprit (it is not), here is the log when the second display is not plugged in:

Running standalone or via steam is the same.

OpenGL doesn't have standardized way to get VRAM size, so we use some macOS specific functions and it seems to fail VRAM size of the dedicated GPU. We will try to improve this for 0.17, you can change the settings manually (the game messages are just warnings)

This should be fixed in 0.17
