One thing to be aware of is that HoloLens is, despite its magical qualities, a fairly limited device. We need to make sure the apps we build perform well on this hardware. Usually I tell developers not to care that much about performance until it becomes an issue. Hardware is upgraded all the time, machines get faster all the time. It is usually cheaper to buy more or better hardware to solve a performance issue than to spend time developing smart tricks nobody understands or can maintain.

On HoloLens, this is a different problem. The hardware is not that advanced, at least not when you look at computing power and especially not when compared to normal desktop based devices. Next to that, we cannot swap components for faster ones. The device is what it is. So, when building HoloLens apps, you need to make sure you have performance on your mind all the time.

You should strive to have your app running on 60 frames per second as much as possible. You can check this in the...
