Think if I'm not mistaken that my nVidia Ge-Force FX 5700 (256 RAM) uses Open GL version 1.4, and, of course, Vue 4 (4.22) can't deal with it, in spite of the fact that ALL my other Open GL apps and games work exactly as they should. Oh well, such is life, and wireframe mode doesn't bother me at all. Well, I'm used to it. Now below I see someone asking about Open GL in Vue 5, and someone else mentioning that possibly Vue does better on Open GL with nVidia than with ATI. I was reading a book the other day about Open GL and if I'm not mistaken, it was invented by SGI and they even have a standard for Open GL, which gets updated every now and then. So, why does the Open GL not work in Vue 4, with my video card, which, by the way, is top of the line, far as vid cards go? What did they do, just write it wrong? Why couldn't they fix it, I mean with all the myriad of threads and complaints there have been...after all, the Open GL deal was a major marketing point for Vue 4, right? How is it that all other Open GL apps on my system can work perfectly, but Vue can't deal with it. More mysterious yet, how is it that Vue 4 behaves so much differently from machine to machine, even when alot of those machines, are very similar in terms of hardware specs (similar cards, CPU's, RAM, etc...) and O/S, though not identical? I have a dual boot: Win 2K Pro (SP 4), and XP Pro (SP 2), and Vue 4.22 behaves exactly the same under each O/S. I'm not really complaining; mostly just curious, because this has been bugging me for some time. If Vue 4's Open GL worked, I would use it, and I would probably like it, like I do with all my other Open GL apps. Thing is, it should work, (part of the marketing, part of the price) and I'm kind of disappointed that E-on never seemed to show a whole lot of concern in trying to make it right, but just steamrolled over Vue 4 on their way to Vue 4 Pro, and now Vue 5, and soon-to-be Vue 5 Pro...
