hi,
I have a huge outside level that is using a lot of fps when the camera is looking where there is alot of models.
I know LOD's can help to do the job, to increase fps, but I have so many models that I just want to know if theres another way to increase fps than to make lower poly models with _1 _2 _3 _4 etc.
Another thing is that my models should not have a lot of poly... I'm using simple cubes with skin to make a building... then when I look at the city, it lags very hard...
Any ideas?
Thanks!

LOD would have very little impact if you have 500+ visible models. I've done benchmarking experiments and found that, for 1000 visible entities, the frame rate is unbearable, even if just 3 vertices, 1 triangle each. What you need to do is combine your models so that they are between 2000 and 5000 polygons each for the best performance and greatest detail. In theory, my city world, of which has nearly 2400 buildings, could still render faster than 100 fps and I wasn't using LOD (but rather over 20,000 polygons and vertices - a bad thing to be doing).  This logarithmic graph tells how the frame rate is for the number of polygons against the rendering rate.

Just 30? Although you should still be getting over 100 fps, the only two things I can come up with is that fps_max is rather low, or your buildings are high-poly. For 64 buildings at 10 polygons each, you should, theoretically, be getting at least 100 fps. Can you post a screenshot showing the debug panel? What is your frame rate (and other specs) when this occurs?

When you start up the game, press the F11 key. The debug panel shows positions, visible entities, and many other useful things that can help. As for taking the screenshots, just upload the PNG, or JPG file to some place like imageshack or photobucket.

out of curiosity, have you changed the nexus at all? I have expierenced FPS increases when I increas the nexus.
