Level of Detail, in theory things look the same but use a lower detailed mesh in the distance. For lower end machines it means you get the same visual performance with better frame rates. Somewhere in the forum there is a quote, "it runs on my machine so why should I bother with poly counts and LOD" from an American content creator. At extremes it means you can run on a standard office laptop, ie Middleton for Laptops. If you're running assets without LOD typically you need an RTX 4070 or above.
Thanks for that John, i know nothing about model creation. The 4070 was all i could afford when i put this machine together in August 2024. I would have preferred a Ti or a 4080.
I'm using a 3070 which runs everything I want without an issue. I think the render issue was a bug with Trainz Plus, pretty sure it was discussed on Discord months ago.
