          Performance is an omnipresent topic in making real-time games. In order to create the illusion of moving images, we need a frame rate of at least 15 frames per second. Depending on the platform and game, 30, 60, or even more frames per second may be the target.

          Unreal Engine provides many features and they have different performance characteristics. In order to optimize the content or code to achieve the required performance, you need to see where the performance is spent. For that, you can use the engine profiling tools. Every case is different and some knowledge about the internals of hardware and software is needed.. The Performance and Profiling pages linked below will guide you through profiling your project.

          Welcome to the new Unreal Engine 4 Documentation site!

          We're working on lots of new features including a feedback system so you can tell us how we are doing. It's not quite ready for use in the wild yet, so head over to the Documentation Feedback forum to tell us about this page or call out any issues you are encountering in the meantime.

          We'll be sure to let you know when the new system is up and running.
