For those experts out there in memory and systems in general - which is more critical for loading large raster images into a drawing - the amount of RAM your system has or the amount of RAM on your video card?
For example - i have a drawing with 6 TIFF images that are each about 330MB. I could load this drawing with no problem in Acad (with Raster Design loaded), but have since changed to Civil 3D (with Raster Design) and can longer load the drawing without encountering a fatal "Out of Memory" error. I was running 1 GB of system memory with a 128 MB video card and have since upgraded to 4 GB or RAM with the same 128MB video card. It doesn't seem to make any difference - the additional RAM still won't load the drawing. Any ideas?
Thanks
