I think in the graphic options, it should be a low end mode you can tick on, which would make it look similar to the way Killer Instinct looked on Xbox 360 during development.

I also think it should be an option to disable the background, and make stages look similar to the practice room. Allow it to be a picture background, so it’s less taxing. This would be beneficial to people who have weaker CPU’s as well.
