If I were you I would just stick with standard lighting; save so much fussing. Use fakiosity to simulate sky light and fill in shady areas (multiple shadow map lights over the sky). But if you really want radiosity, you'll need to:
- reduce mesh: fewer path vertices and fewer modifier steps etc
- keep your subdivision size big
- exclude as much as possible from contributing to light reflection
- (maybe) enable the 3GB switch
