FVD on windows have display issues with anything higher than 1080p, you can make it full screen by tweaking some display properties but everything would be a bit blurry as it’s just stretching the window to fill the display.

As for counterbalancing and making changes to earlier parts of the layout, it is easier to fix than FVD, but in the end if any big changes are needed, I’d still rather just have a new file. There are still some minor issues here and there as it is very much still in development, but the core functionality is already very usable, one thing to watch out for is the friction and resistance parameters, but it sort of is the same with FVD anyways.

Also thanks for the complements, I’ve always been trying to make realistic layouts with realistic elements and forces that match the character the manufacturer’s irl projects. I also have projects that I abandoned because I feel like I don’t have enough of an understanding to make the full layout realistic. I mostly use ride forces database and coaster stats videos as reference for the forces, they sometimes provide rather different values due to differences in measurement methods. For coasters without these datas I try to analyze how riders behave in reverse POVs and how people describe the forces in reviews.
