there have been huge overhauls in lighting optimisation and other optimisations that have helped a bunch, with only more to come to improve performance.
So long as you have a laptop made this decade (a 2011 sandy bridge i5 laptop should be plenty to run the game well), you should be alright.
Intel atom based devices, even with a z8700 or a celeron n4100 might chug a big, but even a core m3 6y30 from 2016 runnning at 10 watts tdp should run cdda well.
if you’re running a core2duo or older, you can find better machines thrown out for free on the side of the road sometimes.
android devices without at least say, a snapdragon 636 or 820, 4gb ram maybe might suffer, but you can get faster devices than that on a budget these days.
