I might be missing something here, or my brain not working, but after rendering to different surfaces for post processing ect... how would you set the render target back to the back buffer?
Right now, I am doing this
IDirect3DSurface9* backBuffer;
_d3dDevice->GetBackBuffer(0, 0, D3DBACKBUFFER_TYPE::D3DBACKBUFFER_TYPE_MONO, &backBuffer);
_d3dDevice->SetRenderTarget(0, backBuffer);
Nope, that's more or less correct (the only thing you're missing is a Release call after you set back - without it you'll leak the IDirect3DSurface9 - and some error checking).
Direct3D has need of instancing, but we do not. We have plenty of glVertexAttrib calls.
