"Out of Memory" on Windows Build, Runs perfectly on Mac Build

Hi all,

I’m running Unity 5.5.0f3 and built out two builds of my game using Mac OS Sierra: a windows build and a mac build. When I ran the mac build on my MacBook it ran perfectly on the highest graphic settings “Fantastic” with the highest screen resolution. When I ran the same build on my PC (Windows 7 64 bit) and my friend’s PC (Windows 10 64 bit) the game crashed with an “Out of Memory” exception on every setting except for the “Fastest” graphic setting. Strangely enough it didn’t matter how high the screen resolution was. Does anyone have any ideas?


P.S. PCs were more than capable of running this game.

Any ideas? I’m certainly out of them.
