How can I make him understand?

So my husband and I both play video games, sometimes we play together. He takes it pretty seriously and gets really angry when he dies and stuff. He doesn't hurt me or anything but he still yells, stomps around, and tosses the controller. It definitely triggers my fight or flight and I usually put on headphones and sit in a different room. I know the neighbors can hear and its embarrassing to see them stare at the house if they are outside. I've talked to him before and he says he will calm down and change what he does. Well that lasted about a week and now he's back to where he was. I usually tell him that he needs to step away or come take a walk with me and he just ignores me. How can I get him to understand that he needs to stop as it literally makes me want to leave when he acts like this?

Edit: he wasn't this way when we first got together and when we got married. I think it was because we lived in an apartment and he knew he had to be quiet.

Edit 2: I just tried to talk to him about it and he got up and stomped to the kitchen swearing under his breath.
