Portals/Rooms: No such thing. The occlusion system is dynamic and autogenerated.

Textures: First of all, youtube videos are crap at using as judge for texture quality. We use 1024x1024 or higher for most textures and a recent map has over 100mb of compressed textures in it and that map is not graphically complete. Considering other stuff take video memory, it would be hard to increase textures further. There are also loading time issues connected with this.
