Subject: added cl_dlights_decayradius and cl_dlights_decaybrightness cvars, both default on... 
X-Git-Tag: xonotic-v0.1.0preview~3470
X-Git-Url: https://git.rm.cloudns.org/?a=commitdiff_plain;h=75272fc2bcb18e2ae872956d0c0d99865500f159;p=xonotic%2Fdarkplaces.git

added cl_dlights_decayradius and cl_dlights_decaybrightness cvars, both default on, this brings back the quake-style radius decay, and keeps the more recently added brightness decay, benchmarks suffered when radius decay was removed, so its return should restore any losses associated with that
