Yes, there are a few problems with the lights- each map has it\'s own lights attached, and then there are more lights added, and others that depend on toher things, etc. It\'s all needed for a fully realistic system, however, it\'s very complex. And whenever something is that complex, it can have problems.
I personaly use -Nolightmapping all the time, but that\'s because I don\'t really care what things look like

I was using 1/16 downsampling for a while, but it didn\'t help my perforamce nearly as much.
Relighting can help some people, but as I posted in the linux forum, it\'s not a good idea to have end users relight. And the maps have already been relighted by the devs, the problem is that the files should be the same but are not. Something is going wrong there, and I have no idea about how
