Enabling WebRender severely impacts vsynctester.com performance #3718

Closed YaLTeR closed 4 years ago

YaLTeR commented 5 years ago

I installed Nightly and decided to check out WebRender. The page scrolling became way smoother than without it, suggesting performance improvements, however vsynctester.com suffered severe performance degradation: without WebRender it gets more or less stable 60 FPS on my setup, but with WebRender it struggles around very unstable 33 FPS.

kvark commented 5 years ago

Thank you for the report! Would you mind creating an issue in https://bugzilla.mozilla.org ? It has a "Graphics: WebRender" component, where Mozilla is tracking all the rendering issues.

YaLTeR commented 5 years ago

Done

dralley commented 4 years ago

@YaLTeR Obviously we have completely different machines (I'm using Fedora 32 w/ Wayland and likely different graphics), but I can't reproduce this. I get a stable 59.9-60 FPS.

Can you reproduce this still on your machine with a stable-channel Firefox?

YaLTeR commented 4 years ago

Unfortunately, I don't have that machine any more. On the machines that I have (one with an AMD RX 580 GPU and another with an AMD Raven GPU-inside-a-CPU) I don't see a noticeable difference.

Darkspirit commented 4 years ago

This issue can be closed.

https://bugzilla.mozilla.org/show_bug.cgi?id=1569673#c2

WebRender has improved its performance with this test since then, and considering that OP no longer can reproduce (and no longer has the original hardware), I'd suggest closing.
