VAM2 performance has been discussed in the VAM discord, and the current info is that VAM2 is more efficient and better optimized, e.g. you can render a higher number of higher higher quality models. Skin physics will be more complex than in VAM1, but will also be more optimized and run (mostly?) on the GPU. Overall though, skin physics will probably cost a lot of performance when simulating the whole body. But things will be more configurable than in VAM1, and I think it's safe to say that any PC that can run VAM1 decently can definitely run VAM2 at a reasonable level of graphical and physical fidelity but not necessarily "maxed out". While there are no official system requirements, I think you're going to be good with any current high-end components. The Intel 155H CPU and 4070 GPU are both great for a laptop, especially if you're planning to just run in desktop mode (no VR).
32GB is recommended for VAM, you will easily experience crashes on 16GB. For VAM2, you probably also want 32GB, people will be adding all kinds of custom assets etc. that will eat up RAM. Even if VAM2 will probably be more efficient for a given complexity of a scene, it will also scale better to more complex scenes where the extra RAM will be useful. Going with 32GB makes even more sense for a laptop where upgrading any component is a hassle.
