Additional options
From Blood Wiki
Darkplaces lighting renderer have a bunch of misc options to tweak.
[edit] Optimizations
For best performance, all optimisations should be on.
r_shadow_scissor : Use scissor optimization of light rendering (restricts rendering to the portion of the screen affected by the light) r_shadow_sortsurfaces : Improve performance by sorting illuminated surfaces by texture r_shadow_usebihculling : Use Bounding Interval Hierarchy for culling lit surfaces instead of Binary Space Partitioning[edit] Light attenuation
This console variables change attenuation for all dynamic lights.
r_shadow_lightattenuationdividebias : Controls the speed of light fading, 1 is default linear fade. r_shadow_lightattenuationlinearscale : Linear scale applied during attenuation, larger values will make lesser half-light zones r_shadow_lightintensityscale : Renders all lights brighter or darker r_shadow_lightradiusscale : Renders all world lights larger or smaller
