I m impressed by how much the Forza devs improved over the years.
I am genuinely disappointed after excellent FH5, granted different teams and FM was always less impressive than GT. Imo GT (which is also mentioned on multiple occasions in the vid) has the best shaders when it comes to car painting, and of course car models are much better. But there is something horribly wrong with materials and reflections in FM, it just looks bad and flat. They still have a LOT to learn.
This is screen grab i took, the reflections are total mess i have no idea what i am looking at here. A lot of reflective materials in game looks super low res.
