Hey, just letting you know I don't own WindowsFX 4 but an email came out saying I do and to download the beta. Just letting you know your email may be going out to the wrong people.
Make sure your graphics experience rating is above 2.0. I installed my nVidia driver but didn't update the experience score and it didn't work until it re-evaluated my machine.
Hi Seabass, I just recently installed Vista Business. I have installed the latest nVidia nForce driver for the 590 SLI chipset. I do not think I've seperatly installed the nVidia display driver yet. I'm having the same issue except that the Window Desktop Manager is running and is set to automatic and Desktop composition is already enabled. I'll repost when all the updates are completed and I have all my drivers installed. EDIT: P.S. I have an EVGA 8800 GTS 320MB video
