FPS problem

[kamilts]

Hello everybody!
First of all , sorry, but my language isn't perfect

And now is my problem. I must build a laboratory where I have something like this:


It's quite big, almost 10 k poly. When I put it into my scene my FPS are drop down to 20 from 50... Is there any way taht I can repair it or optimize my scene. Maybe in TV are any functions that i can speed up my scene?

THX

P.S I can't use any Alpha chanel coz it's very imoprtant thing in my project.
If this thread is't on right place just replace it

I think you must use LOD to prevent it draw every polycons on seen. But im not sure

[micmanos]

If you're making a world (a lab in this case) you should go with a BSP tree. It's faster and allows better culling than a mesh.

[kamilts]

Hmm... BSP tree. If my lab has only to rooms it's a good idea ??

And what about Level Oo Detail? how can I use it(some functions?). I've searched and found nothing.
It's my first time with TV.

Fps performance can depend on a few things. Mainly poly count, mesh optimisations, LOD and Graphics card performance.

I run an nVidia 9400, 128bit, 512Mb GFX card and when I have a scene with 78,000 polys, character animation and alpha blending, I get 115 fps @ 1024x768 in windowed mode.

With this in mind and depending on your GFX card, I suspect you probably have errors in your model. If you have holes in your model or many duplicate and unwelded vertices, or a source texture that does not have the dimensions of the order of 2^n, like  512x512, 1024x1024 or 512x1024 for example, this will significantly reduce the fps. Also you could split your model into segments and load them all to make one Lab. The ones that are not visible will not be drawn by the GFX by default in TV3D.

My lab consist of separate walls. So taht's bad ? I should weld those verts ? But the fps drop down only when I load my object. I don't have any textures and materials yet. I want to finish my model first.
My whole scene has 30,000 polys. So that's quite few.
Split into segments? You think about loading rooms into scene in different objects ??


EDIT:
And another question. TV in my case draw everything on start(?) So, how can I make that TV will drwa only camera view?

[SylvainTV]

No TV does not draw everyting on start. It just draws the meshs that are visible in the camera view.

But yes too many meshes is not very good for the engine and the 3D card. If the walls don't move too often, you could just precompute the entire walls once and in one or several meshes, but not one mesh per wall for example.

[kamilts]

My walls are one mesh.

I have another problem. I made a exe file. It's work on my PC but on different PCs it doesn't work. How can I make my exe to be "multiplatform" ? I should export a TV lib or what ?

[scottpipper]

Maybe youre not getting the right polycount, as your scene in max shows over 50.000 polygons, that can be doubled when you convert the object from poly to mesh or use trinagles instead of Quads, I would first convert all the objects on the scene to mesh, to have the right polygon count, as meshes have the same polycount in TV and max.
If you look at your screen you see that not all edges are shown.

I Can not  get any higher than 11 FPS in Trine,  I have  tried everything but none of tips worked for me to fix my issue.
