about loading some animation model,low fps problem

hey,gays.
i want to write a mmorpg game , i choose irrlicht to render.
i only load 30 ms3d model with Irrlicht. models do animation.
the model vertices: 1200. triangles: 1400. joints: 23 .
in the scene,the fps is very low ,about 17 fps.i don't know how to deal with it.
my video card is 750gt.

now i want to know how to solve the problem.whether is my video card too bad? please tell me ,thanks.

I guess you should compile in release mode for the beginning.

Well, then that's probably the time it needs to animate all those models. Also note that all computations are made on the CPU, so whether or not you have a good GPU doesn't really matter.

Hi Hybrid,
what do you mean by sentence "all computations are made on the CPU, so whether or not you have a good GPU doesn't really matter".??? At engine initialization you should define whether rendering will by accelerated by OpenGL, DirectX or only software rendering. I hope there would be as much as possible computations treated in GPU. Please tell me.

your graphic rendering is performed by the gpu, but the animation action, moving vertices, calculating camera position, collision detention is performed by cpu...

sorry for my low english

*sigh* why does everyone want to _start_ with a mmorpg. You wouldn't start building the empire state building as first architecture project, would you?

Well anyway - we don't really have enough information. A low fps can have lots of reasons. It might have too many animations, it might have models with expensive materials (for examples lots of large transparent polygons), you might do anything in your code which causes slow downs, etc.
