I've been investigating why Train Sim World is such a poor performing game, even on machines like mine with a high end Strix GTX 1070 graphics card and high end i7 CPU. Other Unreal Engine 4 games are much more performant. I am surprised to note that the game seems very poorly optimised? The game renders assets and scenery that the player is never going to see, and more importantly, is performing PhysX calculations on all sorts of guff completely unnecessarily. For example, why on Io is the game rendering the train exterior, and trying (and often failing) calculating the PhysX for break pipes, coaches and the such like, when in cab view? The game needs to despawn the entire train and leave only the cab in place, floating along happily in mid air. The player will not know the difference and you've removed a load of overhead. Removing unseen faces, despawning or using lower resolution / poly models in distances etc. is day 1 game development stuff so I don't need to insult your intelligence explaining that, well, you don't need to draw what isn't going to be seen.... Are there any plans to address this?
