One of the most exciting changes is to shader compiling. Unless games already have their shaders ready, like you see in Steam when it downloads them for you, there will often be a lot of stuttering as the game builds it up with DXVK as you play. That's now changed! If you have drivers that support what's needed, the "shaders will now be compiled at the time the game loads its D3D shaders, rather than at draw time" resulting in reduced or eliminated shader compile stutter. There's some caveats with this though like some games only loading their shaders as you play anyway, 32-bit games may stutter and NVIDIA uses more space.
