Similar situation here. Despite my laptop exceeding minimum specs (at around recommended), it struggles with some content, Rabanastre can be barely playable.
So, I hope it doesnt push it up too much, or we can tone stuff down. Its mainly the OTT particle effects and shadow casting in some areas that can cause problems for me.
I'm playing on a 2020 Macbook, so its not like its an old or bottom market laptop either.
