Map lagging, too newb to know why

[LannFyre]

tl;dr Please download this map + tiny texture pack and help me figure out why my map lags?  If anything is missing, please let me know.  I should point out that the map should be tested as a regular Unreal map, so first person without any of my .u package's actors in the map/game.

Can't open, needs package "Indus1".

Link updated.

"Can't find file for package 'RPG_Game_dev"

lol

[LannFyre]

Links updated, installed a new copy of Unreal Gold to make sure this worked this damn time. There was an actor hidden underneath some lights in the editor, which was giving all three of the warnings of "can't find RPG_Game_dev.u/RPG_Game_music/RPG_sounds".

Nothing special build-wise, must be rubbish code taking cycles.

So you think it is an engine issue? Or do you mean it must be coder (me) error?

[[]KAOS[]Casey]

Code: Select all

function tick(float DeltaDumbassing)
{
local actor a;
foreach AllActors(class'actor',a)
{
log(a$" sucks");
}
}

. . . Casey, I think I missed what you were trying to say.

The engine is fine. It runs fine and it has never been as fine as today with all the effort into making it better.
The map is ultra simple and has nothing special to make it lag.
If you have home-made code, it might be the cause because something has to be the cause of the slowdown.

As for Casey, I guess what he's trying to say is that he has doubts on your competence regarding Uscript.

[LannFyre]

Oh. If so, yeah he's probably right. I don't get why the map lags even when I've taken all of my actors off the map, switched to regular game mode, then moved only the map to a fresh install.

It's not your scripts, it's your lighting. Remove the lights, add some zonelight, and rebuild. Lag is gone.

You have bad settings in your lights. Take the day off and really read this page:

Once you do then take another look at your lights and you will see what's wrong. Here's a hint on one thing (though that's not the only thing with the lights):

Does light really affect performance so badly? I thought you could pretty much add a gazillion lights and the editor will pre-compute them all for you anyway.

Though it looks quite awful, and that link would definetely be a good read :p

I took a quick look and couldn't figure out anything wrong either with the map, getting 60fps on a laptop with integrated graphics.

For static lights yeah, but there are a number of actors, mostly pawns, decos and movers, who use dynamic lighting and have to check against all those lights.
