Sure you can go with a 4K map instead. A lower resolution displacement texture just means your displaced geometry will lose detail up close. But that doesn’t really matter if you’re further away.
maybe there’s a service like render farm that can help and bake it for us?
I’m not sure render farms support distributed map baking..honestly baking shouldn’t take that long to generate (assuming one’s PC has the needed resources). Out of curiosity – what’s your computer’s specs?
