Ok, so what I'm really curious about is the performance in one particular area.

Below is a top down shot of the level in wire frame. Green is where you start as the player, and you are looking down toward the bottom of the screen. The hall which runs horizontally from the red circle to the blue is the longest stretch without any corners, and all of its faces are rendered because they obviously wouldn't be culled.

When you turn into either the red or blue corners and face the hall does anyone notice frame rate drops or stutters? If you do what type of specs do you run?

I'm sorry about not having the debug panel. I didn't know that the templates didn't include it when published, so you guys will have to just look for severe changes visually.
