Crashs when releasing alot of VertexBuffers
Author
In my game, I have tile based maps with each tile having a vertex buffer. When I increase the map size to large, it crashes when releasing vertex buffers.
When I have the map size as 128x128 = 16384 VertexBuffers, its ok, but takes a while to release them all. But when I make the map like 256x256 = 65536 VertexBuffers, it crashes when releasing them all.
Here is my release code:

Anyone have any ideas? The runs perfectly fine, but doesnt crash until I exit and enter the for loops to release all the vertex buffers.

G''day!
Just a thought. Are you checking the return value when you create all your buffers? That''s a lot of buffers to allocate and if some of them fail you may be Release()ing buffers that were never allocated.

Always safe realese directx objects (u know if(object) { object->Release(); object = NULL

SWEET! I figured it out. With an extreme amount of vertex buffers as I have, they have to be released in reverse order of their creation.
My game actually wasnt crashing, it was just taking about 15min to release all the vertex buffers.
But when I reversed the order of their release like so:
it only took a few seconds!
And I have tried maps of size 512x512 (= 262,144 vertex buffers) and it still works fine.
Oh, and of course I do use SAFE_RELEASE.

for (int y = Map->m_MapHeight-1; y >= 0; y--) for (int x = Map->m_MapWidth-1; x >= 0; x--) Map->tile[y][x].InvalidateDeviceObjects(); it only took a few seconds!
