Game lags when using external units for water map

TradeMark · Post by **TradeMark** » 31 Mar 2007, 23:17

I have noticed that when i use extra unit in a map where is water, it will lag when you select the commander (actually only the unit which builds the extra unit...), and when you select the extra unit (for building it), and when you build it.

Map size is relative to the lag length, i just made new map called speed donut:
http://spring.unknown-files.net/file/26 ... nut_20x20/
And that lags damn long at the start

Can someone try to detect where is the problem in spring engine. So it may be fixed at some point?

Any devs going to track the bug?

It must be cause of bloat code.

I just found out that .sdz files doesnt lag at all. But .sd7 files will lag.

Does Spring handle those fileformats differently?

Looks like it does: I compressed my map into 2 megs with 7zip (fastest compression), result: lag. Then i compressed it with zip to 3 megs (slowest compression): no lag.

...Or then 7-zip is just made of phail?

7z decompression is about 6 times slower then zip decompression, IIRC. I made a post about this once (in some thread) but I cannot find it anymore. So basically all (in game) loading from .sd7 files is about 6 times slower then loading the same content from zip files.

But why it even decompresses anything when game is already started?
It should save them to some temp folder.

Or why it doesnt put them all in RAM at once??

not everybody can fit all those files in ram and still have enough left over to run spring well.

How the heck you can play spring, if you you cant read the mod??

I dont understand. All files are needed for making the mod workable.

And mods aint that big, even maps takes like 200 megs. So mods are the smallest problem.

Why not create a cache? Seems like the simplest solution to me...

This might confirm something fang and I were talking about, the 7ziped mods have a frequent issue with desync. Is there a possibility that the decompression offset could have something to do with the mod desyncs?

Solution is here i think :

Yes drolito, as i said .sdz doesnt lag.

This map is fantasctic i think ... it will become a must ^^

Your avatar suits you just right.
Is 7zip decompression really that much slower? Even if you choose bzip2 compression?

Then it isn't 7zip compression anymore

No clue how fast bz2 (de)compression is though, though I'm fairly sure it's slower then zip (de)compression.
