I am on V11.5 landmark windows, I am not sure the last time I updated the video driver. I'm not even sure what that is.

When I am panning around or zooming in my drawing it takes a very long time for each individual object to redraw. We're talking a simple one zoom out or a couple feet pan to the left. Is there any setting I can adjust to speed this up? All my files are simply line objects with either a pattern or hatch on about half of the objects.

I am unable to select certain objects if they are on different layers than the one I have current. Even with my options set to show/snap/modify others. Any way to fix this???

I am working on a colour drawing, every time I move or zoom in and out it takes a very long time and each individual item regenerates. Is there a setting I can put it on to not make it regenerate every little line? I already have the view set on wireframe.
