Is there any way to make BTD6 run better at later levels?

I really enjoy building insane builds and going on as far as I can. But, the game seems to run horrendously at the later levels, to the point where it slows down so much that waves can take like half an hour to finish.

I have a gaming computer, so I don’t think it is a problem with my computer being unable to run the game. Is there a way to make the game run smoother? I really want to do more late-game runs, but the game slowing to a crawl as it tries to render projectiles and such makes it quite an annoying task.
