I am not sure what I am doing wrong, but I can’t hot 60 fps on Gear VR using stripped down FPS template. I am hitting 57-58 fps and 17+ ms render time.
No post process effects (unless fog counts as one, but for example in Unity it doesn’t affect fps), static light, medium quality lighting/shadows, LDR, all rough materials, no view weapon model drawing, etc. Everything that can be turned off to aid rendering/processing is off, there is nowhere else to go more basic than that. The only thing I can think of is skies material, but I doubt it creates such an impact on performance. And yet, can’t have 60 fps stable.
And that is just a basic scene, no spatialized sound, no animated characters and no AI.
Tbh I don’t believe stock UE4 as it’s being provided by Epic (e.g. download via launcher) is nowhere near suitable engine for mobile VR. Unless it has to be all unlit, no shadows, no spatialized sound, no animated characters, no AI game / app. Which isn’t VR I want to offer or experience.
Epic, please do something about mobile VR and please provide templates / examples that give 60 fps stable and isn’t just an empty room with unlit materials!!!
