Hi Annatar! On the slight chance you don’t know but the simplest way would be to change the background color at the start of your code that is to be scrutinized and then to change the color back at the end of your code. This will give you a direct visual output of the consumed rasterlines for your running code. Alternatively, you can read out the vertical beam position at start and end if you like numbers and want it a bit more quantitative. In case you are interested in the used cycles per instruction you can have it the… Read more »
