Draftsight very slow

Whenever i start working with bigger drawings the program just gets very sluggish and starts freezing up. When i check my CPU and GPU usage CPU is only at 10% and GPU is at 50% when the program starts freezing up. So it cant be my PC. Also PC specs are a Ryzen 5 2600 RX 580 for the GPU 16 GB of Ram and a SSD so this should be plenty powerful. All my drivers are up to date.
