19. Remember HW Limits Goals • Frame Rate 60 fps • Memory < 900 MB Total Commit The the biggest factors for CPU performance are: • Too many objects being rendered (try to keep this under 100 unique Renderers or UI elements) • Expensive updates or too many object updates • Hitches due to garbage collection • Expensive graphics settings and shaders (shadows, reflection probes, etc.) https://developer.microsoft.com/en-us/windows/holographic/performance_recommendations_for_unity

20. Optimize Player Go to the player settings by navigating to "Edit > Project Settings > Player" page, click on the "Windows Store“ Use Shader preloading, preloading means you won't see any hitches due to runtime shader compilation. Make sure "Rendering > Rendering Path" is set to Forward (this is the default). The "Use 16-bit Depth Buffers" setting allows you to enable 16-bit depth buffers, which drastically reduces the bandwidth (and thus power) associated with depth buffer traffic.
