I realize that shaders like: Parallax, Matt's Ultimate Lighting pack, bloom and soft-shadowing shaders are written for VS 2.0 and PS 2.0. My question is, has anyone re-written those shaders in a lower shader version? as in VS 1.1 and PS 1.4 or lower since not everybody has the latest graphic cards so gamers might not be able to play if he doesn't have 2.0, If so, please share them with community, thank you
