Frequent Regens when panning or moving across image

This is probably some simple SYSVAR, but we note that after a zoom or two, and/or a pan or two, we must regen to keep navigating the image.  Is there any way to reduce the number of regens we must execute in the course of moving around our images?  These are simple land surveys, and are not complex drawings.  

 

Thanks.

Set REGENAUTO to ON.

REGENAUTO is already on.  Haven't thought of any other variables.  Thanks anyway.

Acad can only hold so much graphics info in RAM and when you're panning/zomming, you're moving past what it's got stored resulting in a need to REGEN.

 

Adding more ram MIGHT reduce the need for regens (I don't know if there's also some sort of internal limit but I DOUBT it).

Does it help if you set IMAGEQUALITY to Draft?

 

Does it help if you toggle RTDisplay (Pan Zoom with Raster& OLE)?

A bit of trivia. The area that you can work in without a regen is called the Virtual Screen. Doing a ZOOM V from the command line will take you to the extents of the Virtual Screen. V isn't listed as an option in the Zoom command, but it still works. V = VMax.

 

A better video card with more RAM might help. But I don't know the specs on the OPs computer.

My system has 16 GB RAM and runs on a 3.40 GHz Xeon E3-1240 64-bit processor.  My suspicion is that the hardware is not at fault.  I know that I could move about freely in vast and complex topographic drawings in LDD, so I think perhaps some sysvar is set here that prevents more than about five pans/zooms in sequence before I must manually regen to continue navigating about the screen.

What is the image file type?

When you say images, are you talking about actual images inserted into the drawing? If so, are you using FDO or MAPIINSERT?

"Image" was a mis-wording for "drawing." It's a Civil 3D 2014 DRAWING.
Sorry.

I was having the same problem working in a drawing with a large topographic surface. Constant auto regen as I queried across the topo made the process take a very long time. I actually turned the auto regen to OFF and the problem seems solved. I am running C3D 2019.
