SVG and VML are langage used by Browser to render vectorial image. In the case of Vector Layer, OpenLayers uses these langages to render features. And what I would like to say is that you are limited by the browsers. Have you test your game in chrome, Google's browser ? If you want to do it faster, you probably have to use mapserver, and générate your map server side. But have you test with marker layer ?
