Q2 2020 WR Perf Notes

Next steps from our WR Perf meeting

Improving Texture caching seems like the best bet for improving perf to unblock Intel Gen 7.5

• Nical has submitted: https://phabricator.services.mozilla.com/D67575
• Once that lands, Jrmuizel to re-measure perf and see how things stack up
• GW to see if he can repro the jerky scroll (frame skipping) on YouTube homepage on his older hardware (https://bugzilla.mozilla.org/show_bug.cgi?id=1576637)
• Nical also to spin off individual bugs for low-hanging texture caching fruit, so we can see what can be potentially done in parallel

Other tasks to prioritize this Quarter likely for GW:

• Segment building - @GW is there a bug on file for this?
• https://bugzilla.mozilla.org/show_bug.cgi?id=1611908

DirectComposition

• How to ship on older hardware?
• Markus, Jeff and Glenn to discuss - see if there is a way to make the artifacting a bit better
• Jrmuizel to see if we can't learn more about why Chrome doesn't ship on AMD

General

• Jrmuizel to take a look more at gen7 Intel hardware to see if there is anything we should do to unblock there
• jbonisteel to take a look at the WR future doc, potentially set up a triage meeting to discuss more
