For optimal performance, enable only the modules you need.
ST running exclusively in real time so that the lighter the session, the faster the interface and the session faster to load.
3D rendering, virtual video screen and motion algorithms involve CPU load. High resource consumption affects the accuracy of automation and can cause saccades.
You can adjust the resolution of the desired computation in the setup / scene menu to balance the CPU load with smooth operation of the interface.
The minimum configuration to properly operate ST requires that your computer is equipped with 4GB of RAM, a 64-bit multi-core processor and a video card supporting OpenGL 1.2 with 512MB of video memory.
The number of audio voices you can manage simultaneously is dependent on the amount of RAM available on your machine.
