In my opinion, your safest bet would be getting Fortnite: Battle Royale! It’s practically the same game, it’s free, easier on the computer (meaning your laptop should run it with ease) and has far less bugs. F:BR is another game that blew up in the genre and many consider it to be better than PUBG.

If you do end up falling in love with F:BR, I’d say it’s worth grabbing PUBG when it’s on sale and giving it a shot. You can always refund it if your laptop doesn’t run it well, just make sure it’s with in 14 days and you’ve played the game for less than 2 hours and Steam will accept the refund! Hope this helped!
