crashes with nvidia + directx dispay drivers

[max montana]

hi, i have big problems with crashes on 2 pc`s with nvidia graficcards.
sometimes the program crashes as soon as i klicked on "show map in viewport" in the mateditor, or moved in the perspective window.

since i changed the display drivers on both pc`s from direct 3d to open gl, everything works fine, and not a single crash happend anymore(before it happend every 5 minutes)
but the performance with the open gl is not that what i expect of a nvidia quadro fx 4600. it is slow when adapt. degred. is impossible(when i zoom with the mousescrollwheel)
before i changed the display drivers i updated the graficcarddrivers with no result. if someone has a solution how i can fix the problems with the direct x drivers, or how i can optimize the viewport performance in open gl, please let me know.

xeon e5420 quad core

nvidia quadro fx 4600

It would be best to stay away from the "Show map in viewport" option for VRayMtl materials, at least until SP2 for V-Ray comes out, which solves a particular issue with this option and DirectX display.

Best regards,

first the problem only occurred with the "show maps in viewport". but then i had the crashes when a map could not be found or when i moved in the perspective window and so on...do you think that clicking on "show maps in viewport" is the cause for the other crashes?

i will change display driver to directx again, start a new szene, never touch the button - and watch if this was the problem.

i think the answer is that nvidia has gone way down hill in quality. i have the 3500 fx and it is the most expensive card the office has ever purchased for me and the worst card i've ever had. (running under vista 64 bit). or they just haven't gotten a hold of the 64 bit os yet. OGL is the only thing that keeps it from crashing. I'm convinced that none of the nvidia cards are made for 3d work. They are all made for gamers so people like us are hosed.

this is damn bad news as i invested so much time in configurating the new workstation. most of it i invested in getting informations, which would be the perfect graficcard for 3d. in nearly every forum(didn´t check vray forum) they told me to buy the fx 4600 - expensive, but worth the money.
the only discussion was, if gamer cards like the nVidia GeForce 8800GT would not be the better decision as they have nearly the same performance as the opengl workstation cards. but i read some post about viewport problems in wireframe mode with the gamer cards, and so decided to invest the money in something serious.

myself i own a 8800GTX and it kicks ass

provided u have the right drivers

the latest nvidia drivers seem to be just fine

although i have to say wireframe performance in large scenes is not so good

For me that translates into this card is not good. How can a card "kick ass" if it bogs down on large scenes in wireframe? That's where i spend all my time. I'm not running computer games, i'm working and building 3d scenes and if a card can't handle large scenes then what good is it? Any card can handle small stuff. The criteria is how it works as the load increases. Are you saying that it works better out of wireframe?

OpenGL will run wireframe better, DirectX's "use cached meshes" option, which caches mesh geometry to the videocard, only works in shaded mode, which is why wireframe bogs down. For me, I've just adapated my workflow to meet these requirements so I do the majority of my work in shaded mode, if I have to do extensive spline and/or wireframe work, I have a separate shortcut that starts max in OpenGL mode for those occaisions.

interesting, because the fx 3500 in shaded mode with direct x crashes/locks up the computer completely. It is worthless with the direct x drivers and even worse with the maxtreme drivers.

My 3500 here at work works great with both directx and Maxtreme in max 9, in shaded bode I can move smoothly around very high poly scenes

I'm on vista on a 64 bit machine. If you are the same then i need to return my card because it must be defective. My card is so bad that there are scenes (that were built on my other computer under windows XP, 32 bit, different card) that i cannot open. The machine locks up on the display locking up the whole computer.

tested my quadro fx 4600 now for one week on a lot of scenes and didn´thave a single crash in open gl. when i switch to direct x, the workflow is gettin much better, zooming, moving even with enourmous polygonnumbers works nearly without delay - but i get crashes...
it would be so nice to get the possibility to use the enourmous power of the card in direct x, has anyone a solution?
(i work with wireframe in ortogonal viewports, and smooth + highlights in perspective/cam viewport)
never tried the maxtreme drivers. where do i get them from, i have a dell precision t7400, and there are no maxtreme drivers on their homepage.

It doesn't bog down, it's just that in smooth and highlights (or other views that wireframe) it's just so god damn impressive. I've got an 8800 and even the wireframe is good on really complex scenes, but it's just the difference between the two modes that makes you think that...
the 8800 is amazing.

64 bit vista or 32 bit xp?
