I have a blueprint that makes a materials flicker between two colors at a set frequency determined by a looped event tick with a set delay. This should run on the Oculus DK2, which is supposed to run at 75Hz. So if I set the delay to 0.01 seconds for example, will the color really change every 0.01 seconds? How do I confirm the accuracy of the color change frequency at the output (which is the DK2 screen in this case)?
