Meta Quest Browser & BabylonJS = Slow FPS
I'm trying learn about WebXR and I'm finding that my library of choice isn't playing well in the Meta Browswer, locking at about 30 FPS. Now, I see 60 FPS on the desktop with Chrome and I know that's because Chrome is locked in a vsync. I can pass Chrome some parameters to unlock the FPS limiting. At that point, I'm seeing around 500 fps. Chrome works great with Link, but I'm looking to work with the native Meta Browser inside the Quest. I've found other engines, such as the Wonderland Engine, demonstrates 72 FPS in the Quest with their app Escape Artists (https://esc.art). A-Frame applications show up in the browser at 90 FPS. So my question is, is there some sort of parameter or command the WebGL lib should be passing to the browser to speed it up? Or, is this likely to be some sort of bug in BabylonJS that is locking it to 30 FPS and the browser doesn't have any sort of artificial rate limiting?
How can I change the Splash screen Title?
Hello everyone. I'm developing a UE4 game using 4.27.1. I was wondering how can I change the splash screen title that appears when I first launch my game. The only solution I found was to create a new Target.cs file with the name I want as title. Is there another way? without creating a new Target for my UE4 game? Thanks!
Engine for research
What's up folks! I'm a PhD student researching human perception of light and colours (yes I'm aware of the research call :) ). I'm looking to investigate the perception of these aspects when viewed with an HMD (more specifically the Rift CV1). I have some experience with rendering, however I have no experience with game/VR engines. I'd like to use an engine that is capable of rendering as realistic as possible (HDR, PBR, spectral) but it seems to me this is simply too slow to use in VR. So my question is threefold: 1) Which engine yields the most realistic images? Hardware is not really an issue here (university fuuunds). 2) Most likely the results of the engine from Q1 won't cut it, so I'm thinking of rendering photorealistic spherical renders and viewing them with a Rift (no parallax I know). Ideally, I could walk around in a scene with the engine from Q1 and, with a press of a button, render such a sphere (with an external renderer such as Octane) and view it when ready (hopefully this is in the order of seconds). Is this AT ALL possible and if so, which engine would be best? 3) I'd also like to be able to let matlab change parameters in the engine while running (such as polygon count, tone mapping, maybe load another spherical render, ...). Again, is this at all possible and if so, which engine would you people suggest? Thanks for taking your time to read this and thanks in advance for the feedback/ideas! Michiel
