There are almost no particles and the background is a simple plane... disabling that will not bump the framerate from 7 to 60. ^^;
and map details? (Like as grass, rocks, etc;)
These are not details, they are also just static images that are part of what you walk on. If you disable the grass, the ground also disappears. I'm afraid there is nothing I can do to support hardware this old, I'm sorry. :/
ok u.u
