If you get a Quest 3, it should play those kinds of games stand alone, no problem. No gaming laptop required. If it is going to be a more graphically intense game, or the games are only on Steam or whatever (so needs Steam Link), you are going to need a gaming laptop with a discrete GPU (released from the last 3-4 years). To do the wireless link, you’ll need a wifi6 capable access point/router, and wifi6 capable chipset in the laptop, or a dongle, or a gigabit ethernet cable from the laptop directly plugged in into the access pointer/router.
