One thing I've found that does make a difference to Poser is the version of OpenGL support. When DAZ 3D did their special deal on Hexagon, I found that I needed a video driver upgrade for everything to work properly. I don't know if Vue could have changed anything. There are two quick checks you can make. In Poser, it's possible to switch off the OpenGL requirement. It's also possible to reduce the hardware acceleration setting in Windows. If either of these have a beneficial effect, get an updated driver. And go to the manufacturer. Windows Update just isn't current on this.
