Testing your computer

The tests below will help you determine if LightAct runs as it should.

No GPU Throttling

If you open Preferences window and enable Remote support mode, then you'll be able to modify the Vertical sync property in Project settings window.

Make sure it is unchecked and also uncheck Force Project framerate. This will cause LightAct to run as fast as it can.

On an average computer you should easily achieve more than 1000 FPS. The exact number is not so important. What's important is that the FPS should be more or less constant.

You can observe this either by watching the FPS number in the top right corner of the program or by opening the Performance window where all the graphs should be more or less completely straight.

If you see framerate dips every few seconds or so, it means something is throttling your GPU.

Smooth Traveling gradient and Strobe Content Overrides

You can now re-enable Vertical sync and Force Project framerate checkboxes in Project settings window. You can also uncheck Remote support mode in the Preferences window.

Then, in the Output Maps window, create one virtual output of the same resolution as your output display. You can do that by simply double clicking on one of your detected Physical outputs. Then enable either Strobe or Traveling gradient override. Enable the output so you see the chosen content override on the output display.

Traveling gradient content override.

Traveling lines content override.

Strobe content override.

Regardless of which of these 3 content overrides you picked, the movement should be completely smooth.
