3D views choppy

[David J. Potter]

3-D performance is determined not be CPU speed but rather by the quality of one's video hardware (video card) and how fast and how well it can process video (pictorial) data per second.
Kat mentioned "...at least 256 Mb dedicated,...", my video card has 1 Gb and is quite adequate, anything less than 1 Gb will give less performance. Many laptop makers will advertise large amounts of video support in terms of Mb or Gb but you have to look past the sales pitch to see that this is not dedicated support but integrated support (the video card shares RAM with the rest of the Motherboard which always then delivers poor performance for Chief Architect and Home Designer software).

Home Designer software is relatively inexpensive but does require above average PC hardware to support its functioning well.

Thank you both for the reply, but I fail to see why the FIRST laptop I purchased, the one with the separate Nvidia graphics card with 2GB of RAM ALSO failed to produce smooth scrolling in 3D views. The original PC I tried this on was a Toshiba Satellite C655D-S5518. It has a Radeon graphics engine on the motherboard, not a separate video card. The Toshiba specs for that laptop state it has "384MB-1459MB dynamically allocated shared graphics memory". In other words it shares the system RAM. And it functioned flawlessly.
I still think there must be a compatibility issue with the Intel graphics on the motherboard which I currently have.

Don't really have enough information on that system to comment. Are you sure the NVidia was the only video on that computer?

Some laptops have both an integrated chipset, which is used when the laptop isn't plugged in (to conserve battery life), and an actual video card which is used when it's plugged in.
