Hi Stephen,

AS 4000 doesn't work well with Win7

1 - Upgrade Hardware

You don't describe your video card and processor specs however, there are some basic parameters
- If you have an onboard video card you can't upgrade just the video card, because it is an integrated unit, but you can update all the drivers
- In my opinion, onboard video cards and chipsets(almost all of them) have low performance for rendering purposes
- In my experience, just a better video card doesn't solve the issue--> you'll need a good "render set"--> good processor (2.6 GHz or up)+ plenty of memory (4 Gb or up) + a good videocard (512 Mb or up).

2 - Punch files

- If you are working with a heavy file, including lots of furniture, topo, etc, you should upgrade the hardware elements, but the issue is more related with the file
- If you have a slow performance with any Punch file (with just a wall, for example), then yes, a hardware upgrade is in order.
But even this, will depend of the computer / processor you have. All the elements work together as I stated above

3 - Tips

- Click on the pencil/plan icon (dependingng of your versions) at the top of the LiveView window (Render and Navigation Options). Clicking on the different icons you can disable temporarily the lights or 3D objects, or topo etc. This will speed the rendering during the working process

- Use View--> Render Clear view--> use this during the elaboration time

- Try to apply the 3d objects (cabinets, furniture, etc) and topography at last

- You can turn off the "Undo" feature--> Edit--> Undo preferences. This will speed your work. Just remember to save frequently (because this step deactivates the autosave for backup feature)

- To get a good Punch performance, close other programs, including the e-mail. Perhaps, other programs are using resources otherwise required in Punch.

Hope this helps
