It’s far too early in Crowfall’s testing to worry about optimizing the game’s frame rate and overall performance, but there’s a difference between “optimizing” and “improving.” The latest change made to the game exists precisely in that space, as the game should now perform better just because the game’s terrain is now being rendered using custom-built meshes instead of built-in Unity meshes. That… had a pretty distinct improvement on the rendering and overall performance!
Why? Well, the game’s engine no longer has to convert from default options before rendering things, which cuts down on processing power and results in terrain that should look identical but just render more smoothly. There’s also a new way of handling the grass rendering that significantly cuts down on processing as each chunk of the landscape is rendered. All of which should result in an improvement you see in terms of frame rate, but the game itself shouldn’t look different… which is a performance upgrade for you, really.
