This is my first post here so I'm hoping that everything is right.
I've been using LDD for quite a long time. In the past, it was installed on my Desktop Computer running Windows Vista, and nothing went wrong. I recently bought a Laptop running Windows 8.1 and again installed LDD to continue building my projets. After a few weeks, problems started to appear. LDD would sometimes crash or auto-terminate unexpectedly under a number of situations, meaning that I would suddenly loose everything unsaved! At that time, I was building something important and the issues made me very frustrated. Although I managed to complete it, I decided to contact LEGO to see if they could help me come up with a long-term solution. Soon, the problem was identified.
LDD has the following requirments: Graphics card: 128 MB graphics card (OpenGL 1.1 or higher compatible). However, my Laptop did not meet that requirment, as my Intel HD Graphics 4400 only has 32 MB of Dedicated Video Memory.
The Support Team of LDD suggested that I should instead use the NVIDIA GeForce 840M also equipped on my Laptop to run LDD as a possible solution. I did just that, and it seems that everything is back to normal again, as I could successfully open and modify some old files. New files created were also error-free. But eventually something still went wrong.
The imoprtant something I was building which I mentioned above had a file size of 696 KB, while my current Project has a file size of 420 KB. The ironic thing is the larger file can finally be opened and modified successfully but the smaller one can't! Here is what happens: After I open the smaller file, it starts to load. When it nearly finishes loading, LDD crashes or auto-terminates, so I simply can't open the file to continue building the project! The only special thing about the smaller file is that it has very large dimensions. Its base consists of 32 48x48 Base Plates in a 4x8 arrangement, so the actual dimensions are 192x384 Bricks.
As I do not want to change any of the hardware on my laptop or get another one, can anyone suggest me a solution so that I can continue to build my project on my Laptop? If you have a similar problem, do post your reply and see if anyone can help you here. Thank you for your attention.
