Thanks! My global settings are listed below. What do you suggest I change?

global_settings {
    max_trace_level 30
    ambient_light rgb <1,1,1>
    radiosity {
      pretrace_start 0.08
      pretrace_end   0.01
      always_sample 0
      //save_file "radiosity_data.inc"

      //count 20
      count 1000

      nearest_count 10
      error_bound 0.05
      recursion_limit 5

      low_error_factor 0.2
      gray_threshold 0.4
      minimum_reuse 0.010
      brightness 1
      max_sample -1
      normal off

      adc_bailout 0.01/2
    }
  }
