Hi I am experiencing poor graphical performance of draftsight on windows 7 64bits with a Intel Sandy Bridge 4C/8T, 16 GB DDR3 RAM and a brand new Nvidia Geforce 1660super, with medium to heavy weight DWG, and I have noticed this also in a client's computer as well with a Win10/64bits system. Slow clunky wheel mouse zoom in out and a simple line offset takes more than 3 seconds. Noticeable in DWG bigger than 2MG, big problems in DWGs beyond 10MG. I need a fix for this issue please.
