A WHQL-certified ForceWare release for Windows Vista is expected before the end of February. Nvidia also plans to release another update in March with GeForce 7 SLI capabilities and better TV output support. April is the month where support for DirectX 10 SLI and H.264 video acceleration is planned to be addressed.
