Thanks for getting back to me. My launcher has General, Install, performance, mytrainz and dev tabs, but none of them have vsync. I've seen screenshots of other people's launcher and they have a vsync in the general tab right under the full screen drop down.
I’ve seen a lot of forum messages about performance that mention a VSync setting. I have trainz+ standard and I don’t see that setting. Is it only available in certain versions of Trainz?
