As a former telecom guy who helped tons of people with their internet I’d very much like to discuss your internet quality
So I’d say yeah, it’s most likely your internet. And no, mbps doesn’t mean jack if the connection to the central is poor.
I won’t sell you the idea of streaming games, but both me and my wife have a good time streaming when we’re playing together. Very rare does it lag or drop in image quality. Heck, even Flight Simulator 2024 is a blast to play on my phone
Hope Playstation comes with this feature soon too, I strongly dislike that multiplayer nowadays means online and not on the couch same with two controllers.. very limiting for kids when they have a friend over and want to play something(I remember LOTR Retorn of the King as a kid. That multiplayer experience was awesome), or if you have a husband or wife that you like to play with after the kids are tucked in for the night. Dual TV & console setup is too expensive. Not to mention utterly ridiculous. We need more oldschool multiplayer games..
