Most new Core 2 Duo laptops run on the 945GM motherboard chipset. This chipset uses the new embedded Intel 950 Graphics Chip. Envisioneer does not work on the 950 graphics chip.

I believe opengl support for the 950 chipset is only at opengl v1.4 which may be the problem. Unfortunately, most new Core 2 Duo laptops will be using this chipset.

If your in the market for a new laptop to run envisioneer, make sure you stay clear of machines with a 945 chipset and 950 graphics.

[edit]
This refers to Envisioneer V4 running under Vista on a laptop.

Are you talking about onboard graphics?
Doesn't seem to affect performance of a HP nw9440 which has a Quadro card.

Thanks for that info. Is this situation because of  shared video memory and not dedicated video memory card
 Does CADsoft have a viewpoint on this? Is it true that Envisioneer will not run on Core 2Duo processors?

G'day Chris!
One of my builders has an HP nw9440 & it runs E4 without a problem. However, it has the 945PM Express chipset. The blanket statement above "This means you can't have a Core 2 Duo CPU in your new laptop." is incorrect
It has a T7600 C2D processor & Quadro FX1500M video card. It flies!

Thanks Merv. Hopefully it's not a sitiuation of 'suck it and see' when buying a new one with anything less than that. I suspect that the problem lays with 'shared access' memory. It won't be the first time. Still, as I'm in the market for a newy at the moment, all users info is treated with respect and with the utmost paranoia

I'm talking about core 2 duo laptops which use an Intel 945/950 chipset combination. It appears to be due to poor opengl support in the drivers and zero directx support by cadsoft.

Sorry if this is too technical, I'm a software engineer not a draftsman.

><snip>< It appears to be due to poor opengl support in the drivers

What operating system are you referring to? 64bit?

and zero directx support by cadsoft.
Sorry if this is too technical, I'm a software engineer . . . .

afaik 3DSmax is the only high-end CAD modeller that has moved to DirectX. Most still use OpenGL.
It would be appreciated if you can provide some links that would educate me on the pros & cons of OpenGL Vs DirectX & if I've been misinformed.
What is your experience to cause you to make the blanket statement above?

Sorry, I won't be entering into any discussions or debates on anything. I have however cleaned up my first post in an attempt to avoid sections of it being reused out of context. I do not own a copy of cadsoft, I don't use it, I don't need it. I was simply engaged by a client who has been dealing with cadsoft.au for the last week in an attempt to get it going.  I thought I might warn other people of this problem before they purchased. I certainly won't bother next time.

No need to be like that m8. The whole idea of the forum is we all help each other.
It's decades since I started studying Engineering but I'm certain the same analytical problem-solving principles I learnt then still apply:
[list=1]

• Gather all the facts & present them in logical fashion.
  
• Document all efforts used to try to find a resolution to the problem.
  
• When asking for help have all this information ready[/list:o]
  If you could do that we all might learn something.
  Out of curiosity, did your client try disabling hardware acceleration?
  Unless your client provided Cadsoft Australia with all the particulars  the chances of a prompt, satisfactory solution are slim.

  Until such time as you can provide evidence for your statement . . .
  

  Envisioneer does not work on the 950 graphics chip.

  we can only assume you're trolling for some obscure reason.

[edit]
This refers to Envisioneer V4 running under Vista on a laptop.

Just for future reference, my Asus V9520 is labelled OpenGL 1.4 & the only problem with Env4v1 is floating toolbars that lose the plot when I toggle between model view & worksheet view but I believe that's not related to OpenGL.
Final comment: The old adage holds true."Generally, you get what you pay for." Buy the cheapest components at your own risk.

After having spoken with local CADsoft, I believe that there is no issue if all the drivers are written for Vista, which means open GL. Some drivers have not been updated as yet, and it pays to check on web for video driver versions b4 purchasing I suppose

The 945 motherboard /950 graphics Intel chipset combination is the most popular on the market for Core 2 Duo processors in laptops. If your new core2duo laptop costs under AU$2000 then it's most likely a 945/950 combo.

Every opengl test and every other cad (computer aided design) and cam(computer aided modelling) program available works with this chipset. Cadsoft does not.

An Asus V9520 is either a Nvidia graphics card or a Laptop with a nvidia card. The HP nw9440 machine you first mentioined costs over AU$4500 for the basic model and has a high end embedded nvidia video card.

I'm talking about the 950 graphics chip. You obviously have no idea what your talking about when it comes to hardware. Please do not fill this thread with gibberish making it impossible to search for.

I've passed my test results back to MSI and Intel.

Shouldn't be an issue.
The word is that Microsoft is going to continue shipping computers with XP now. Too many issues with Vista. And a lot of $$$
