FPS setting
Most project in 24fps
VR projects at 90 fps
game at 60 fps
Look for an interactive workflow
Deferred Vs Forward render
Default Render
Default UE4 Render
Store the raw data into Screen Space Buffers(Color, normal, Depth,etc)
Lighting is evaluated at "light" draw time
Extra screenspace data can be used for more sophisticated post process effects and simpler combination of lighting methods(SSAO,SSR)
Support all the rendering features
Forward render
For VR
