So I was reading the Proposed Portal System thread and most were talking about relogging because of lag caused by porting. In school today we were talking about concepts of rendering. I never have had to relog until prolly 50 or so ports. Is it possible to change the rendering landscapes into text files that stay text files until the character is within that area and then they are rendered?

Example:
Draw a table 4 columns and 3 rows and number them from left to right 1-12.
If a character is in box 6, then squares 1-3,5-7, and 9-11 would be rendered and 4, 8 , and 12 would be text. If the character is in box 7 then 2-4, 6-8 and 10-12 are rendered and 1,5 and 9 are text.

This possible/feasible? Or would it just mess things up??
