Hey there! Are you by chance using Parallels or some other VM?

Can you email us at eromancergames@gmail.com? We've made a Parallels build for users with this same issue.
And yep there's a setting in Unity that changed which gives Windows users much better performance, but unfortunately it's incompatible with Parallels. We eventually plan to add Mac and Linux builds.
