delay after zoom or pan

Ben Jedrej

I am experiencing quite long delays after zooming or panning with either mouse wheel or through the pan or zoom command and am getting quite frustrated. I have a fairly new toshiba satallite with AMD A10 cpu, Radeon R6 graphics card and 8GB RAM so surely can't be poor computer performance can it?. Any help would be appreciated.

In addition to the usual advice to check the global and application-specific settings in the Radeon control panel, run the REDSDKINFO command within Bricscad. That will let you see which GPU you're actually using (as in CPU vs GPU) and whether it thinks that your drivers are up to date. Won't necessarily fix the problem but it will give you an idea as to whether the rendering engine is happy with the hardware setup.

 Thanks Richard,

Not sure wha tthe differnce is between the Local and Selected GPUs but downloading the recommended driver anyway and see how that goes.

I'm not sure why the term "local" is used. "Detected GPU" would probably be clearer. In my case, the notebook PC here has one GPU as part of the Intel chipset that mostly takes care of the desktop and regular applications and a separate nVidia GPU that handles the heavy lifting for 3D rendering; it's that one which is the "selected" GPU.

Updating the graphics driver to Redway's recommended version is probably a good idea. Do take the usual precautions, make a system restore point, etc.

Check your settings look for 2d Graphics device use GDI

 Thanks Richard and Patrik,

Now running with latest driver for GPUs and have check settings for 2D graphic device is GDI. Still getting frustrating delay/lag even while trying to do simple tasks as drawing lines. The drafting is not complicated just 2D with some xrefs none of which are particularly large nothing over 1MB.

Perhaps upgrading to v15.3 will help?
