why is this rendering?

Lol, that really describes completely useless always open areaportals.

Here's my ye old Bounce remake map. The above picture is the released version (just weeks after the SDK got released and everyone had little knowledge) and the below picture is after I added areaportals into it (when I learned what they did):

No it's not normal for that area. And when I am standing way back in that area and it's all rendered my fps is 50.

Could you share that "mat_wireframe 2" screen ?

Zyndrome speaks the truth. Areaportals that are always open will still help, since the player has to have direct LOS to them for them to render the area behind them. If VIS is giving you a hard time about certain corners or something, add a always open areaportal around the corner and it will sort itself out.

The best way to see them in action is having a look at the dod_flash map source, they're demonstrated nicely near the middle of the map.

god im itching to look at your vmf:P

I'm itching to help your itch.

Its not about the position that your are in thats calculated what can be seen, but what the visleaf you are in can see.

Those models could be with a tiny small corner in a visleaf that can be seen from youre leaf position and then get rendered,

if its that big of a deal, you can use occluders.

Occluders and areaportals come at their own cost, so they must have a big enough influence to be worth it.

Open areaportals are still usefull as they more accurately calculate whan can be seen by the player.

But for the most part you will need them just so seal off area's so you can use the areaportal windows on other locations. (as area's can ' leak' as well)

Official css maps that I know that use areaportals are cs_compound and de_dust 2, altough I doubt it matters much how its used in dust2

well dude, maybe you should try remaking that single area and see if you get the same issue

You may be good with areaportals but good lord I never want to see another un-func_detailed torus again in my life!

Maybe post a BSP if you can't find out what the problem is. Hard to tell much from that screenshot, and mat_wireframe 1 is so messy.

And here's a screenshot that shows Areaportals in the works on my map (2 screenshots merged), with 'r_drawportals 1' : http://www.shatteredminds.net/skit/areaportals.jpg

Gives you an idea how they work practically.
