To anyone who wants to upgrade... I would wait for VAM 2 to release... because from what I tested in the alpha, it runs WAY WAY WAY better than VAM 1 on lower specs pcs.
Yeah, since there in no physics, or strand based hairs, clothing with physics and all of goodies.
Even Beta 1 will work much better than VaM1, cuz it still gonna miss all of that.
Turn off all colisions, hairs, clothing and VaM 1 will run butter smooth too.
VaM 2 will only bring better rendering, which might be less or more demanding for GPU, depends of settings which might be more configuratable.
As far we saw lightning gonna be much less demanding in base form.
VaM 1.0 settings have close to zero impact on decent systems in desktop mode.
It gonna bring also multi thread physics, which we have no info at all atm, since Meshed didn't showed any progress with that - it's planned for Beta 2+ i think. This will be the biggest game changer. But, still we know nothing, aside Mesh gonna write his very own system for that.
Once all of the good stuff gonna be implemented, guess in like 1-2 years, VaM 2 still gonna just crush top tier PCs at the time.
