Sounds like a use case for a good product or program, but it’s a hard problem to figure out game performance without installing and running. Soooo many videos online where people install 8 different games to manuallytest framerate, and none where they look up a ready value.
You could first look up the laptop’s GPU, and try putting it into a GPU compare site, score it against a GPU you’ve known and try games you’re familiar with.
If it’s just an Intel GPU, you pretty much know you’d only play basic 2D/lowpoly indie games, if which there are many.
