Hi, With my Geoforce2 and OpenGl activate, all the 4 vue (up,face...) are not refresh when I move an object. Is it a well-knowm bug or an "Don't touch this option kiddo" activated ? For exemple, I move the cam from postion A to B, I saw the cam in both but only the B is working. If I refresh the screen, the problem is still alive. thanks for the info Laurent

Salut Laurent,

It's a well known "problem"...

The Open GL implementation in VUE 4 doesn't work correctly. With most of the Open GL graphic accelerator cards you get very slow refreshing rates and display/shading problems.

My 64 Mb GeForce 4 gives me real time texture mapping and very fast refreshing rates with many 3D softwares. With VUE 4 it slows the 3D view refreshing rate and causes many display problems. I had the same troubles with my previous card, a GeForce 2.

The answer from e-on is : "it's a problem with the graphic card driver".Well, I have the standard nvidia driver for GeForce 4. I really don't know where I should get another one...and I'm still waiting for a list of compatible GPU cards/drivers.

Unless e-on can give you a solution, your only solution is to disable "use Open GL" in VUE4's option.

But you know, graphic acceleration cards are not as important than we think : The triangles (polygons) are always calculated by the program itself. So even if you have a high-end graphic card, your CPU will do most of the job. And for rendering they are totally useless.

oki, it just for information purpose. Merci Eric

I use Vue 4.10.02 and a Radeon 8500 card and it is OK with me, I move an object in a view - the others follow.

I have a GE Force Card and had similar problem. There is a fix for this on e-onsoftware.com website, look under FAQ or support. They tell you to remove a dll for the GE Force card that forces Windows to use it's own open gl driver. I did this and it work, though I have heard that doing this can effect games that use open gl, I'm not a big gamer and haven't had any problems (knock on wood) working in Vue since I did it.

ok, i will try it. Thanks for the tip

It's indeed a problem of NVIDIA's driver set. Vue uses multithreaded OpenGL rendering in different windows, something that can produce problems for NV drivers (see below). You can fix the issue by disabling the "background rendering thread" in Vue's properties (just above the OpenGL bit) or falling back on Microsoft's software OpenGL drivers as suggested by Tomsde. I have been bugging NV about this issue for some time, now, but it's very low on their priorities list, apparently. For some reason, Vue seems to be the only program that doesn't work properly with multithreaded OpenGL rendering (other professional OpenGL applications work just fine). It's probably an issue that has to be resolved by NV and e-on in tandem, i.e. NV will have to review e-on's code to provide some solutions for e-on to implement. I doubt NV will change their whole OpenGL drivers architecture just to please Vue users. ;) ta, -Sascha.rb
