One of the top reasons for not getting WebGL is the AMD blacklists. Here's a histogram of blacklisted versions from WebGL failures: {u'6.1.7600.16385': 3, u'8.33.0.0': 1, u'8.420.0.0': 1, u'8.471.0.0': 1, u'8.479.0.0': 1, u'8.522.0.0': 1, u'8.56.1.15': 3, u'8.56.1.16': 5, u'8.593.100.0': 5}) I think we should consider reducing the blacklist to 8.56.1.15. The current choice is AFAIK arbitrary and comes from bug 792190

That sounds reasonable. Anthony, if we were to do this, we'd want to track the overall crash numbers for the drivers that we'd allow in (8.56.1.16 and 8.593.100.0), perhaps some others, and track to see what effect, if any. Jeff, would you want to start by just enabling WebGL on these drivers, blocking the rest of the features?

I think I would unblock everything, but I don't feel very strongly about that position.

Overall, and what we'd consider "graphics" crashes.

It's worth noting that 8.56.1.16 is a version that shipped with Windows so if you installed windows and never enabled updates you'd have this driver.

(In reply to Milan Sreckovic [:milan] from comment #4) > Overall, and what we'd consider "graphics" crashes. I've added prototype that allows graphing any driver version (all vs graphics): http://ashughes1.github.io/metrics-graphics-gfx/#driver_lookup Simply enter the driver version and click 'graph'. With this we should be able to graph *any* driver version upon request, not just the ones above. Hopefully this serves what's needed here. Let me know.

A reasonable driver to compare to with is probably 8.631.0.0. This is one of the windows update drivers that we currently allow that came out later that year.

The reduces the blocklisting to the version of the AMD driver that shipped with Windows 7 RTM. I've tested out that driver on hardware in Toronto and everything seems to run fine. I ran the WebGL conformance test suite and it only failed a couple of tests. I expect it will fail the same tests with our currently accepted driver but I will double check.

Release Note Request (optional, but appreciated) [Why is this notable]: [Suggested wording]: Windows computers with AMD graphics and driver versions between 8.56.1.15 and 8.62.0.0, previously blocking graphics hardware acceleration, are now allowing it. [Links (documentation, blog post, etc)]:

Milan - Here I think this would be nice to say, but without linking to the bug or some explanation it is hard to express in a short release note. Maybe some of these perf improvements and other things you are suggesting for relnotes could be explained in a blog post and then we could note and link to it from one general release note.
