Spent a couple of fun packed days trying something out. I have 4 boxes each with different mobo's. Three have GeForce cards (v0, v3, v4) and one has a Radeon 9800. OS's are 98SE, W2K, XP Home & XP Pro. CPU are varied too. I have tried every combination of BIOS, driver and config setting I can think of inc. nVidia reference drivers and swapping cards between boxes. There's no way I can get consisent OpenGL performance with Vue 4 on any combination of the above. Also reading this thread, and earlier ones in the Vue forum, it seems that there is no mobo / graphics card combination that is guaranteed to work. I have taken to Vue in a big way recently but let's face facts here: ATi and nVidia are the market leading cards so if Vue doesn't work with them then the fault lies with E-On not our hardware. Case of the tail wagging the dog....

Cheers,
Mark
