also, Nvdia cards seem stabler than ATI, PC is much more solid than MAC.
See my tutorial in signature on import optimization as they can take an assload of resources.

Totally disagree that PC is much more solid than a Mac.

I have been using Vue on a 2008 Mac Pro since Vue 7 and although I duel-boot into Windows 7 Ultimate 64bit for heavy scenes, most of my work is done fully inside the Mac OS. I can tell you that I have had very little problems at all with any major crashes with Vue 7 or 8 on the Mac and it has been stable in that regard. Right now, there are some things different between the Mac and PC version, but once the 64 bit Vue 8 is released which they are working on it will be a moot point.

I would advise looking at the threads here as suggested and seeing if anything helps. Also, while nVidia seems to be more common, I know at least two people using ATI 2890 graphic cards with no issues.

Sure they have, as I noted in my prior post I know two people using ATI 2890 cards and no major issues. Except of course for the software bugs which they keep working on during the year.

Quote - I just compared the 1st 10 pages of Vue and Bryce galleries. The oldest image in Vue gallery was from February 9, 2010 4:00, the oldest image in Bryce gallery was from February 9, 2010 5:20. So, the difference in posted images is very, very small.

Also, I think a lot of Vue users don't necessarily lable their gallery uploads as being from Vue.  Whereas Bryce users (in general) always labels their uploads as coming from Bryce.

ATI AGP Radeon X1650 512MB.  Works just fine in Vue 8 Infinite 47776 with WinXP32.

Thank you very much for that, gillbrooks and vintorix!  OpenGL redraws are much faster now.  The clouds come right up in my main camera view of the sky.  I used to have to sit and wait for them to generate.  How was this setting discovered?

wasn't me, learned it from someone else. Wabe?? :)

"How was this setting discovered?"

Neither Google nor Cornucopia3D yelded any results but in a Renderosity forum search someone mentioned Vue.run. Via Vue.run I found the config folder then I did a search of the value I knew I had for my videocard setting. Just ordinary vulcan logic, ;)

Radeon 5850 here. Opengl 2.1 shader4 in use with no extraordinary problems ;)

Vue 8.4 allows editing the video memory limit from the options menu now.  At least in WinXP32.

As far as ATI cards go, I started years ago with a free version of Vue 3.5, got 5 inf,, 6 inf. and just upgraded to Vue 8 Inf. During that time I've used:
9700 pro
9800xt
850xt PE
1950xt
4870
5870
So far, up to Vue 6 I've had one graphics related issue that involved one specific driver. Vue 8 is giving me a bit of a slow response (at least with the one render I've worked on so far). However considering that -a) It's originally a Vue 6 file, so it could be simply an import issue.
b) I'm still using XP pro 32 bit. Not only am I limited by the 2G address limitation, but also by older software.
c) it's a relatively new card and I haven't gotten around to updating drivers yet.- I really can't complain.
As far as Vue issues go, I agree with Rutra. You have to spend some time optimizing your computer. While I don't have a computer dedicated to CG, I placed a shortcut on my quicklaunch bar to disable my internet connection and I have anitvirus software that can be disabled. When I'm working in any graphics program, my internet and my antivirus are turned off. My system visual effects are set up as"adjust windows for maximum performance." I'm also pretty fanatical about crap that runs in the background unnecessarily. My systems tray has nothing outside of my time/ date icons except my antivirus - and that's off when I'm working on CG. If you take a quick peek at my gallery, you'll see I use a whole heck of a lot of poser imports in my renders and I rarely, if ever have major issues. And anybody whose uses the Vue/Poser combination can tell you that poser imports are resource pigs. And with one exception, I've used whatever gianormous texture maps that Poser used, rather than reducing the file size as is usually done.
