After loading a background file, the quality of the image is very poor. This typically occurs for image files, like .TIFF and .JPG files.
This is related to the video card driver on the workstation. As a quick test, trying restarting the computer on in Safe Mode and run the software. You will likely see the quality of the image will be improved. This is because the computer will use a generic video card driver. You can also test this on a new machine.
To resolve the issue, try updating the video card driver on the workstation. You can also try a different background file type, if possible. Shapefiles and .DXF files are useful as backgrounds because they are already scaled, meaning you do not need to enter the coordinates for the corners of the background file.
Note that the CONNECT Edition release introduces some improvements with regard to memory management of background layers, which may help.
Long time to load background layers
