Check for resource consumption from the task manager and monitor if any resource is being used 100 percent. You can do it in many ways: try Windows screen splitting and run different applications, that is, task manager and the Roblox game simultaneously. After observation, if you get to know that any component has the most usage, reduce the burden from it to avoid overloading.
