Hi everyone. I was writing a game engine that supports multiple APIs (i.e. Both Direct3D and OpenGL for Gfx, DirectSound, XAudio and OpenAL for audio, and DirectInput and XInput for input devices, via plugin system, etc). Everything is fine except for my Direct3D driver's initialization. I'm using IDirect3D9::GetDeviceCaps to determine support for T&L HAL on the users card. At first it worked fine, but ever since I updated my drivers some time ago, it always returns 0. I use D3DCREATE_HARDWARE_VERTEXPROCESSING and it works fine. Is this really a problem with NVIDIA's drivers? Or is there a better way of detecting T&L HAL? Thanks.
