Hi! I'm new at Gameprogramming with DirectX and I've got a problem. I'm coding in Visual Basic 6.0 and DX 8.1! Now my problem: When I want to render a big outdoor surface with some houses and trees I have a very bad performance and this without Sound, AI or SpecialFX, like fire-effects. I know that I have to divide my surface into little tiles and I have to proof if the surface is visible or not. And so I would get a lot more performance. BUT HOW TO CODE IT??? So, if anyone around here knows a tutorial or some tipps: Please post them here! And: Yes I've searched via google! PS: Please excuse my bad english, but this is not my native language!

Thanks Auron!

I've found some tutorials about culling, but one thing I don't know is how to get the vertex data out of my D3DXMesh.

Am I right that I have to get the data from my .x-file into a vertex buffer to divide it into smaller parts?
I know how to get an array of vertices into the buffer, but not how to do this with an .x-file.

I recommend "Tricks of the 3D game programming gurus" by Andre Lamothe to anyone who is even thinking of writing a 3D game.
