laggy low poly zoned level

[bobtheking]

i have a level, the average polycount is 150, the average node count is 400, and i have zoned the level. why does it run at 15 fps, while my other levels (higher poly, unzoned), run at 30-45?

The only thing I can think of right off hand is ...
Do you have any dynamic lights with overlapping radii? (radiuses)
.
That could make the engine chug a bit.

Tha'ts the first thing that came to mind too me as well. Use any semisolids? and is the 150 ingame or in ed?

[Hourences]

how big are the zoneportals ?

[@kuma]

the average node count is 400

[Laff]

yep, nodecount is the issue ;)

[bobtheking]

4 semisolids, 150 ingame, the max is about 220. i got one view with 40 polys, and it was running at 18 fps. all but 6 of the zone portals is 256x256. the others are slime, and one is a flooded room. i have one dynamic light, it is a busted light fixture that flickers. what about ambient sounds, i have quite a few of those.

[Hourences]

hmm weird

not the ambient sounds, perfectly possible, unless you have a trillion of them

[LXIXGTO]

I didn't know that (or if ) too many sounds would
affect frame rate in the game.
.
Maybe you could use the radii viewto see
how many of those sounds overlap eachother?
Just a thought. :)

i think i figured out what it was, i have a lot of railings, and they have a chain link fence type thing between them and the floor. it was a grate texture, scaled down .0625 or whatever. apparently it also scales the light maps, so i did high shadow + low shadow, and scaled it by .125. it seems to have cured the problem

AFAIK, if you can see through multiple layers of masked textures that will kill the framerate as well.

[AMmayhem]

So a higher node count will slow the map down too? I didn't know that. Or did I misread something?

[Bot_40]

Nodes slow the map down more than polys. It would actually be more sensible to use nodes as a measure of how fast maps are likely to run.

i think i found the problem.

Hm:

Just how many zone portals do you have? Dont get so worked up about the benefits of zone portals that you over-zone your level. . .

How do you get quotes to display the original poster?

[bobtheking]

i have 22 zones (i think, but quite a few are slime. i have one in each pipe connecting the rooms.

click the quote button under their post, far right bottom.

i have increased the fps a lot by deleting the chain link fences to around 40. (i have a crappy computer, you 5 ghz with geforce3s don't fret) now i have another problem, it lags when i put bots in, doesn't seem to happen in my other levels.

[Balton]

the only thing I can suggest you is naming that map different. there have been several maps called sewer... jsut to avoid stress

[bobtheking]

i know, it is just a temporary name so i can save it.

[GoldenMouse]

I've started using DM/CTF/DOM-Working for my maps. So far, no CTF-workings just yet. Anyway, that map is looking nice from the vantage provided. Could ya drop me a line when it's done?

[bobtheking]

Could ya drop me a line when it's done?
and how would i do that, i am relativley new to these forums.

[bobtheking]

i forgot to say, it is sooo close to being done, all i have to do is iron out the botpathing, see my other thread, 'stupid bots!', for details.
