To speed things up , the ground effects and details like houses and trees can come later, like in some kind of free download.
Just concentrate on maps and flyable modules.

EDIT: Maybe an extreme/super ground effects package could be sold at a later date. In my limited experience , cpu's, v-cards, drives and memory can slow a system down if it is over taxed. Thus those without the latest hardware could still play it.
