irr vs 3ds

I'm making a game with a large landscape/terrain/call it whatever you want. I'm deciding which one should I use. I'd rather use 3ds since its easier to work with it but i dont know if exporting to .3ds from blender supports lights like exporting to irr.
So, which one would you use?

Just tried my physics thingie with both .3ds and .irrmesh, with .irrmesh I had over two times more FPS

irrmesh with lightmapping, good choice but the problem is, if ur map is huge(really huge, like IGI 2), it will slow down ur system's performance. try some other light mapping application(use googling), that export 3ds, x or any other formate that irrlicht supports

So i tried the 3ds format and i'm getting some pretty cool results. What in .irr format loaded in about half a minute now loads in a second. I think this is clear for me

well the loading time is due to the fact that 3ds is a binary fileformat and irrmesh is xml based and has to be parsed which is quite slow. you could create a binary irrmesh format

Is there any tutorial how to do that?

well not really....
first you have to layout your format then write some functions to write the mesh into a file and then functions to load it. that will then be as fast as 3ds loading.

Thanks.
I think i will stick with .3ds for now

How long would it take to load a list of model files and locations?
Is it possible to pre-parse the xml without huge files?
