>Even AAA games these days happily run on GC languages.

Which games are these? Are you referring to games written in Unity where the game logic is scripted in C#? Or are you referring to Minecraft Java Edition?

I seriously doubt you would get close to the same performance in a modern AAA title running in a Java/C# based engine.

Unreal Engine has a GC.

You're right that there is a difference between "engine written largely in C++ and some parts are GC'd" vs "game written in Java/C#", but it's certainly not unheard of to use a GC in games, pervasively in simpler ones (Heck, Balatro is written in Lua!) and sparingly in even more advanced titles.

I think Balatro uses the Love2d engine which is in C/C++.

		Sure, but you write games in it in Lua. That Love2d is implemented in C++ (GitHub says like 80% C++ and 10% C) doesn't mean that you're writing the game in it. In my understanding, Love2d uses reference counting (which is still GC) for its own stuff, and integrates those into Lua's tracing GC.

Unreal Engine has a C++-based GC.

C#? Maybe. Java? Less likely.
