Naughty Dog historically disagreed with this [0], plenty of games these days are developed in languages with GC but it is a performance trade off. For maximum performance any Lisp is probably not the way to go but I don't think it's unfeasable.

I want to say in general e.g. SBCL (a popular common lisp implementation) will perform a lot better than Racket. Racket is a great language but performance is not it's strong suit.

Currently, but hopefully no longer in the near future, SBCL’s garbage collector is extremely meh. It’s hard to tune, it stops the world, etc.

Otherwise SBCL is a wonderful implementation.

I used Clozure CL (and I'm now a LispWorks customer) for this reason.

Is there some recent work going on in SBCL on its GC?

[vindarel]

yes!
