[jiri][for 0.17][0.16.27] OS X:Incorrect determination of VRAM
Posted: Thu Mar 01, 2018 5:17 pm
This is probably not particularly high priority, but thought I'd report it anyway. I have a Mac with two GPUs, the integrated one on the CPU and a separate discrete GPU (hardware is a 2016 MacBook Pro 15" with the Radeon 460 GPU). When starting up, Factorio reports the wrong amount of VRAM; the discrete GPU has 4 GB, not the 1.5 GB reported. This matters because the game won't let me use the shiny new HD sprites even though the hardware meets the 3 GB or more minimum requirement (if I try to switch the sprite resolution to high in Graphics Options, I get an error dialog telling me that 1.5 GB isn't enough).
What appears to be happening is that for some reason the game is getting the value of "VRAM" assigned to the integrated GPU (which, according to the Mac System Info report, is indeed 1.5 GB) rather than the discrete. I've tried forcing the discrete GPU to be active before the game starts up rather than letting it switch over automatically, and that makes no difference.
