WebXR issues with Link Cable using Quest 3 and RTX 4090 - Graphics Gods please save me
Hey I'm having performance issues with a WebXR app that I'm working on specifically when connected to Oculus Link and viewing the app with WebXR through PCVR. I expected my RTX 4090 would make it faster but I'm getting worse performance. I've tried profiling on mac pro, quest 3 standalone, and link cable (quest 3). Link cable is by far the slowest and I'm not sure why. My beefy GPU should make the scene render faster shouldn't it? For this particular webgl scene, the per frame gpu time is less than a ms on my mac pro when using the emulator and using the webxr emulator on my windows pc yields about the same. Once I plug in, the gpu time shoots up to 10-15ms. I've run the oculus profiler and it reported a min-max of (0,20ms) and an average of 9ms. This is a super small scene with only 60k vertices so I'm not sure what's going on. I ran profilers and verified that my CPU and GPU both have enough headroom. They're both <50% utilized. I don't see any abnormal Garbage Collecting in the chrome profiler. I've tried a bunch of other stuff I read on forums like disabling Hardware Accelerated Graphics Scheduling, uninstalling MSI afterburner, updating drivers, and a bunch more. I can't for the life of me figure out why my macbook and the quest 3 standalone would be outperforming the 4090. Any tips or advice would be appreciated! Happy to provide performance or log traces too.
Is there any way to develop a custom Meta Quest browser (for WebXR ) in PCVR?
I want to develop a PCVR WebXR browser application: A browser that supports browsing WebXR content, computed on the PC, per Quset Link to Quset 2 header and do Interaction as normal. In short: a PCVR with Meta Quest browser's WebXR capabilities. Purpose: To open a large and complex WebXR site. The site runs on the Quest 2 header for comparison and has reached a performance ceiling. I would like to build a browser in PCVR that supports the experience of WebXR content. Question: Is there already a compliant development kit, or browser package? Previous attempts: FirefoxRealityPC(FxRPC) Unfortunately, the project has been discontinued. : End of support for Firefox Reality After trying, it didn't achieve the function I wanted
