Hello everyone. I’m doing research on how games made with Unreal engine are optimized. One of the best examples of this is Fortnite. There are actually many test videos on YouTube. I have a 3060 graphics card and I use an i9 12900 processor. On a computer with the same features, Fortnite can be played 360 fps at low settings. The problem is that we cannot see these fps values even in unreal engine demo templates. Open an empty template in unreal engine, just put 10 empty cubes. Turn off lumen, nanite and turn all settings to the lowest. Despite this, you cannot see 350 fps. So how does Fortnite do this? How can it see such high fps values in such a comprehensive and online game?
Try setting RHI to DX11
Make sure the frame rate is uncapped
Test with a packaged game and not in editor
Profile the game
Also Epic released a bunch of talks and material optimizing Fortnite for mobile, worth checking out.
