I've made a model with 2000+ polygons and have it rigged with multiple vertex influences (with character studio's biped as bones) and exported it with pandasoft. But when I made the model loop/play, the fps decreases from 70-100 to 10-20.(But when the model stopped, the fps increases again) Any ideas/advice what's the wrong here?

Nothing wrong! It just takes allot of time to calculate the position of each vertex so you are bound to see a performance hit. Mind you, that seems like allot of loss!!! To help speed things allong, try making allot of the vertexes influenced by only one bone in max, and make sure that you don't have vertexes influenced by more bones than they need to be. If its a character you are talking about, the joints should be influenced by two bones each, and the rest of the body should be rigidly attached to the corresponding bone.

Thanks for the advice!
But just wondering... Any other ways on how to make this thing faster without changing the rig? (i had hard time doing that...) But i'll be working on it anyway.

i think something is odd, i have the same problem in one of my games and i havnt sussed it yet. I have just one boned model which is basically a gyroscopic sphere spinning on two axis with two bones - the model itself is only 800 polys. loading it is fine, without it animating i get about 90 fps in my already quite full game, setting it to loop kills the fps to about 30 though.

I refuse to accept it as in my shisaku project i have tons of animated models like a fully boned human model for the player, boned spiders with multiple joints down the legs etc - several of them all loaded and animating with some pretty complex animations and no hit to fps. There must be SOMETHING odd with my gyro but i really cant tell what it is, let me know if you figure whats doing it with your model and likewise i'll tell you if i find out with mine :x

Mach:Everything count towards performances.

-If you can,cut down some polygons that the texture can simulate.

-Reduce your textures to half until you start seeing a visual difference,then go back to the last state where you didn't.

-Is it possible that you've put too much frames for an animation that could require less?

-Whenever you can,and whenever it won't look bad,try using the legacy DX7 jointed models

I tried making everything rigid (0 or 1 in weights) but still the fps is very low. Anymore ideas?

If I made this model have a lesser polycount, then how come most of the console/pc games with their characters having more than 2000 polys run at a good fps? I think darkbasic is the prob about this...

Here's the model that makes my game hell slow...

Yes,it's partly DB's fault but it's not true that console games all have high polygons models.

I've seen too often people talking about the FF or fighting games polycounts but how many players are on-screen at the same time?

Check out massive games like GTA San andreas,they're usually topping the polygons as low as they can to save on overall performances and keep some of it for the levels...and it still looks and plays great!

What format are you running in DBpro DirectX or 3DS?

*EDIT* never mind, see you've exported using panda.

But it would be helpfull to see the rig in any case.. I've done some animation earlier.. and there was a smal drop in preformance.. but not near the amoung you've spoke of
