WHAT IS RACER?

Racer is a free car simulation project, using real car physics to get a realistic feeling. Cars, tracks, scenes and such can be created with relative simplicity in mind (compared to other driving simulations). The 3D and other file formats are, or should be, documented. Editors and support programs are also available to get a very flexible and expandable simulator. It uses OpenGL for rendering.
It attempts to do well at the physics section, trying to create life-like cars to emphasize car control and doesn't cut back on realism in the interest of fun. If you've played Grand Prix Legends from Papyrus, you'll know what I'm talking about.
