We have installed the latest version of Autocad 2015. The problem is everytime we use the Copy / Mirror or Array Commands, the system will freeze for 5 seconds. We did not have this issue on previous versions 2014 or 2012. We have since upgraded the graphics cards to 2GB Nvidia cards.
Running Windows 7, 64bit
Intel i7-2600 3.40GHz
16 GB ram
Anybody else experiencing these problems or know of a solution.
