BUGS:
The textures on the poles, when compared to everything else, are ew. Change the textures. That is not a bug.
The teleporter that allows you to exit from the bottom floor is facing at a slightly wrong angle, when you go through, you hit the wall if you don't turn right away. Now THAT is and I find that annoying especially when I want to run through the teles over and over and over again.
On the top level, there's a cave area that serves no purpose that I can think of. Isn't that where the flag spawns in CTF?
As Masterz pointed out, shader_models don't fit in with the level. Change the bitmaps on the shader_models to something a bit more detailed.Not a bug
Come on some of those aren't bugs that would affect gameplay.

And my average FPS in this map is lower than the what I got in the last beta. D:
