Problemas graficos en Linux con drivers radeon

[Ermides]

hola desde que conozco regnum nunca ha corrido bien graficamente en linux usando los drivers open source radeon.

a día de hoy mesa 3d y los drivers radeon tienen soporte completo para OpenGL 3.3 pero regnum sigue con los mismo problemas, como es posible de todos los juegos de valve, Metro: last light, Trine 2, Wargame European escalation, etc se renderizen correctamente y este juego no.

aqui pongo una screenshot del problema y lo que muestra la consola.

el modo seguro es una solucion a medias, se renderiza bien el personaje pero el resto de mundo no, no hay nieve en el suelo ni callendo del cielo, no hay grama etc.

espero que los desarrolladores tomen en cuenta esto porque regnum ya es hora que se renderize correctamente en los drivers radeon así como lo hace con los intel usando mi core i5 2500k.
