VBGamer

I need help. I have just upgraded my grpahic card from a VooDoo3 to a Rage Fury Pro. My games all look exquisite now. The only thing that now doesn't run is my own VB/DirectX code. Elaboration... It is Direct3D It runs, but the frame rate is slower. (from 90ish to about 17) Alphablending is either on (for everything) or off. I cannot control it for specific Vertices as I could before. Finally - fog doesn't work at all? I am choosing the HAL device specifically, so am a bit lost. Any ideas....?? I thought DirectX was meant to deal with all this nonsense.
