1660Ti is the bare minimum entry lvl gpu for a 2020 computer
Get off your horse brudda...
You know what is the most popular GPU used by Steam users? 1060... what's the second most popular? 1050Ti - these two together account for almost 20% of all Steam users when it comes to 3D capability.
If you take all the variants and flavors of 1060 and comparable GPUs - it's more than 35 % there. And I'm not even talking about lower than that.
I think some people need a reality check, as if everyone rocks 3080s or some such. A LOT of people game on laptops and these are the GPUs you can overwhelmingly expect there.
BG3 is no Crysis, it does not push revolutionary graphics, so I am not so sure why you are going such "pikachuface" over prospect of it running on MacBook Pro - which it perfectly will be able to do.
