Following the installation of the latest version of drafsight (2018 SP2) on a new laptop (ASUS VIVOBOOK I7, SSD and HDD) I hear a high-pitched noise in the PC during the operation of Daftsight... I only have this noise with this software and it attenuates a little when I reduce the performance of the PC (switching to battery only for example).
I'll come back to my post, it seems that this crackling comes from the CPU (which would explain the decrease in noise by lowering the performance). It's surprising because I only have this noise with draftsight, and not with other software (QGIS, AUTOCAD...).
