LT is different in terms of what you can do with 3D, and that is where you
need the extra graphics. With LT, the old GeForce card should be fine as
long as it has 128 MB of video ram. Also CLASSICLAYER does not work with
LT. I really wish it did.

The newer AutoCADs tend to chew up a lot of graphical memory for all the WOW
factor visual effects. Try looking into your graphics card acceleration, and
possibly turning off some of the visual bells and whistles if you don't need
them. A big complaint is the Layer Properties Manager palette, and a lot of
people have found immediate performance improvements once they switch back
to the classic dialog box. The command is CLASSICLAYER.
As for slow saves, in my own experience I found the SAVEFIDELITY system
variable to be the culprit behind extremely long saves. When turned on,
which is the default setting, it will translate annotation objects into
multiple copies in different scales and on different layers, for users of
2007 or older platforms. It also translates them back into a single object
with many layer states again. This takes time. I went from 5 minute saves
down to 13 second saves when I shut mine off. I also read a similar post
yesterday with the same solution and it worked. If you have no users of 2007
or older in your office anymore, set that to zero. You can still save down
to 2007, and just keep in mind if you deal with outside users with 2007 or
older, you can always turn it back on just for saving and sending them your
work. I hope this helped!
