1196984 - (perf-gaming) [meta] Gaming/Web VR enhancements to perftools

Status: RESOLVED INVALID

(DevTools :: Performance Tools (Profiler/Timeline), enhancement, P3)

Description

[Josh Carpenter [:jcarpenter]]

Performance in WebVR is the difference between feeling like you are truly inside a virtual world or feeling like you're going to throw up. For WebVR to be viable, we must consistently deliver the performance required for a pleasant (ideally presence-inducing) experience. Focusing on

* Frames per second (ideally 90hz, which is Oculus CV1 refresh rate)
* Motion-to-photon latency (ideally sub-20ms)
* Judder (ideally none. FPS is solid and tracking never freezes or skips)
* Tracking stability (accurate, never skips or freezes)
* Resolution (all of the above at the Oculus CV1 resolution of 2160×1200)

This bug is about putting in place the testing infrastructure to measure the performance of WebVR in Mozilla products.

Triaging. Filter on ADRENOCORTICOTROPIC (yes).

Covered as part of oculus perfhud work https://bugzilla.mozilla.org/show_bug.cgi?id=1238436

There may be dev tools specific features we can add for webvr, but that can be another bug since the perfhud covers the primary items listed in OP.

Oops, reopening since I didn't see that this was a meta.

This report is related to the old DevTools Profiler.
The Performance panel now points to the new Firefox profiler available at profiler.firefox.com
