Unsure which game on Switch you're referring to, but satellite internet has a lag of over half a second which will cause many real-time games to run slow.
It has nothing to do with available speed. It's caused because of the distance the satellite signal has to travel, much like when you see a time lag for live, remote newscasters on TV.
Welcome to the community and thank you for posting. I just wanted to add that it's possible there's something going on with the Switch itself or the game, independent of the internet connection. I don't have much else to go on due to the lack of other details, but just something to consider.
I'm closing this thread since it's gone inactive. Please start a new thread if you have any concerns regarding the HughesNet service.
