Question about Hardware Accelleration

Hello everyone
I don't know a lot about CAD and 3D, so I hope you will be able to help me.
One of my users are running ADT 2005 and Autocad 2004 on a HP NC8000 laptop
with 512 MB of RAM . This laptop contains a ATI Mobility Radeon 9600 Series graphic adapter with 64 MB RAM. When my user enables 3D Hardware accelleration i ADT, the performance is slower than if he's not enabling hardware accelleration. The system is using the latest videodriver available from HP. Don you need to do anything apart from installing the videodriver and enabling Hardware accelleration to make it work, or is the ATI adapter just not capable of perfoming well?
yours sincerely

To the best of my knowledge Autocad does not use hardware acceleration. The 9600 has pretty good hardware acceleration, and if Autocad were ritten to use it, would be a suitable product, but if Autocad does't use the hardware acceleration, I don't see the point of a sophisticated videocard on the machine unless you are also using it for gaming.

Sounds like you need more RAM. According to the specs, the minimum for 2004 is 512 megs; 2005 and 2006 require a gig. The programs will still run with less, just slow as molasses. The more RAM the merrier--you will really see a difference. Don't bother getting more than 2 gigs, though. As currently configured, Windows doesn't recognize anything over 2 gigs.

Hello Marc So the use of Hardware Accelleration raises the need for more RAM? I was begun to think, that it could be an issue of the ATI Radeon Mobility card not being fully OpenGL compliant. The laptop is running quite acceptable when Hardware accelleration is not enabled.

No, the actual program requires more RAM. Read the "Minimum System Requirements" in the manual or on the outside of the box your ACAD came in. It's spelled out pretty clearly. It may be that your laptop has enough brute force to calculate its way through a CAD session despite theoretically not having enough RAM. It will definitely run better (you may be pleasantly surprised) with more.
Not sure about your hardware acceleration question though. ATI is a very reputable graphics card.

Jakob,
Autocad ADT 2006 requires 1GB of RAM?? Why????????
We just upgraded our desktop from 256 to 1GB thinking we'd be in the clear for a transition to 2006!

Well I run both with 512MB and they work well enough
