AutoCAD LT 2014 Flickering Issue

[LKrijgsman]

autocad LT 2014 keeps flickering when i only have 3 drawings open with Xref in it.
the size of each drawing is about 2-3 MB.

My pc specs are as following:
- 8 GB ram
- I5 processor HP Pro3500
- NVIDIA Quadro k600 1GB graphic card
- operating system windows 7 professional.

i tried the following options:
- install the .reg file.
- start up under diagnostic
- Reinstal autocad
- put the drawings on hard disk instead of server.
- disabled hardware acceleration or enable

all of the above didn't have any effect.

the specs of the pc are average.. what can be the problem?

I detected that the performance log in autocad LT sees the graphic card as not tested and supported.

According to the site from usa.autodesk it says that de quadro k600 is recommended.

the driver on that site is installed but stil autocad LT sees it as not supported.

Start at the end of this thread an work back as needed, different tips worked for different folks: http://forums.autodesk.com/t5/AutoCAD-LT-General/AutoCAD-LT-2014-Flickering-Issue/td-p/3875348

Ensure LT2014 is fully patched and updated too.

i might need to recall the issue "Flickering"

i tried several solutions neither work.
the aeccore.crx file isnt even in the folder from autodesk...

but its when i pan and zoom that its going really slow.
in the bottom right corner u can see all symbols flicker and switch for a minute or 1-2.

This is the solution the Autodesk offered:

The aeccore fix was a peer solution and Autodesk frowned upon it.

tried the .reg file already several times but for some reason today it worked. for now at least.

thank you guys for your help.

That file worked a treat.

We have found that when old files are used this flickering happened, but when we created new template drawings from scratch, they worked fine. We still haven't pinpointed it, but we think that there is something corrupted that creates the issues, like a  block or hatch.  This is why it only happens to some users and not everyone. How old are you're files that you are working with?

it are all imported drawings as Xref.

The are new but i guess made in Revit and only the top view got send to me.

I have upgraded the graphics card since then and now i dont have the problem anymore..
