I''m trying to create an index buffer but I keep getting E_OUTOFMEMORY. The size my prog is trying to allocate is 996 bytes. I shouldn''t be out of memory. I tried making it smaller as well but that made no difference. I tried both 16-bit and 32-bit indicies. As well as how it is allocated and usage flags.. This is stumping me... Here''s the line of code: ret = Display->D3DDevice->CreateIndexBuffer ((Mesh.numTris * 3) * 2, D3DUSAGE_WRITEONLY, D3DFMT_INDEX16, D3DPOOL_MANAGED, &Mesh.Indicies); arggg -Zims

Surely you''re using the debug runtime and it''s of no help?

I''ve seen this bug on Dual Processor computers. You have to specify the multiple CPU flag when creating the D3D device.

I figured it out. I was a little hasty in posting to the board as I was getting a bit agrevated.. Turns out it was the CreateVertexBuffer code before this code that was screwing it up.. I neglected to note that the size parameter was in bytes, not number of verts.. back in dx7 this was number of verts, so I guess I kinda just assumed.. (This is my first forray into dx8) I was creating a vertex buffer that was way too small and then running amok in memory filling it with verts. oops.
