RTMC Run-Time has been known to run slowly when there is a lot of animation going on alongside graphs that are updating quickly. The default setting for frames per second (FPS) is 10, and it can be adjusted under Edit | Preferences. A setting of 2 or 3 FPS may be better for some displays. It may also be helpful to adjust the quality scale of the graphics and disable the animation altogether. Pipes, motors, and animated GIFs often create issues. It may be helpful to place real-time components on one screen and historic trends on another.
