I have a brand new Mac with gen10 i7, exactly the same config as in a Win machine I got.Windows: smooth at medium settingsMac: barely playable at ultra low settings. I looked for the config file as they mentioned on the Internet for adding vRAM to the program, the file seems not even be there.. What's happening? Why does a lesser OS like Windows give tons of more frames compared to a better UNIX like OS? Stange...
