Hi, Having a station with two virtual controllers (RW 6.13.01) connected to a ‘S7-PLCsim Advanced V16’ through ‘Simit V10.2’. I’m using Robotstudio 2021.4. The PC I’m using is a Dell laptop 7760 32GB with a Nvidia RTX A4000 discrete graphic card and I have enabled the discrete graphics card in the file “robotstudio.exe.config” (se pic). There are some jerky movement in the simulation when creating a copy of a graphic component with the function “Source” at the same time when the robots moves. The task manager never report more than 40% on either CPU, GPU or memory. What can I do to improve the performance? There are some settings for graphics in robotstudio and there are also many settings in the Nvidia control panel, any suggestions? I also have a problem that sometime only one of the controllers connects to the PLC when starting the station, a restart of the affected controller solves that problem. ![image.png](https://europe1.discourse-cdn.com/flex005/uploads/robotics1/original/2X/d/d3ddad9a6f675d81e90e0871c7e40cdbdcf17ad9.png) ---

I doubled RAM & it sped up my simulation speed significantly. I have 64 GB
