Hi, I've been using vue since v2 and bought the v4 upgrade as soon as it came out. I've a couple of questions which have been bugging me for a while and thought I'd ask for some advice. Does anyone have good OpenGL performance with an NVidia card. I've tried v4 on a GF DDR,GF2 MX and a GF3 and the performance is rotten. All 3 of these cards can throw polys around in huge numbers and I don't have any complaints when using LW6 - I suspect it's something to do with the multi threading. Even so the display rendering speed when the background thread is turned off is very slow. Any ideas - driver problem ? Also - since installing the patch I don't see any preview pictures/atmospheres when I try to load an atmosphere/scene - I think something has gone wrong here. I'll try a reinstall. It's really the OpenGL thing that bothers me as it's essentially useless and is unuseable. I have to go back to goold old wireframe display. Any hints etc greatly appreciated
