If you mean obsession with shadows, I have an obsession with shadows, too.
I once put 6 DynamicLight entities (talking about CryEngine 1) hoping the 6 sharp lights would make a blur effect and give an illusion of 1 realistic light + shadows. I got 6fps, but it was totally worth it.
Hmm... I might also show this: This is my old school map which I made in 7th grade. This year I decided to give it a facelift because I was going to play CS 1.6 in school. The new one (if anyone's wondering) will be quite different, and will probably come out next year when I get to high school. (see, my elementary is right next to the high school, so I will still be able to work on it, and expand the map into the high school :D)
I'm extremely surprised that AllocBlock didn't even reach 60%.
Though, I'm sure that -notexscale -chop 2 -texchop 1 would work well too.
(well, barely, because hlrad.exe would take a few hours or a day, and it would need a lot of RAM)
