Chrome's perf dropped from 60fps to 30fps on webglfundamentals.org |
||||||||||||||||||||||||||
Issue descriptionChrome Version: Version 69.0.3497.81 (Official Build) (64-bit) OS: MacOS 10.13.6 What steps will reproduce the problem? (1) On a 2014 15" Macbook Pro go to https://webglfundamentals.org What is the expected result? The background moves buttery smooth at 60fps What happens instead? The background moves at 30fps at best stuttering Note: still runs smooth on v68, and Firefox and Safari Ran bisect and it came up with You are probably looking for a change made after 580180 (known good), but no later than 580211 (first known bad).

I think we can do a better bisect internally. ligi: can you assign someone from your team to do a finer bisect? Hopefully we can pin-point to a single CL.

I'd already started a per-revision bisect. Here are the results: python bisect_builds.py --use-local-cache -o -a mac -g 579000 -b 589893 -- https://webglfundamentals.org You are probably looking for a change made after 580212 (known good), but no later than 580213 (first known bad). CHANGELOG URL: The script might not always return single CL as suspect as some perf builds might get missing due to failure. https://chromium.googlesource.com/chromium/src/+log/cf64e143fc871fae4bc0522241294d34b832c33f..989f7a704c225521f08b2a0d7f64c619ba8aea29 It's the debugging information that was added for release blocker Issue 863817. Chris, can that be removed at this point?

I suspect that this is being caused by FlushForDriverCrashWorkaround, which prevents GPU raster context from crashing at abnormally high rates. This flush may be removed for WebGL contexts.

Thanks Chris. Let me try removing that.

This regression should be fixed by the above change. We can consider back-merges if this appears urgent (i.e., on more sites).

Able to reproduce the issue on chrome version 69.0.3497.81 (build without fix) as per the comment #0. Verified the fix on Mac 10.13.6 using Chrome version # 71.0.3549.0 . Attaching screen-cast for reference. Observed that "The background moves buttery smooth at 60fps" The fix is working as expected, adding Verified labels Thanks...!

Requesting merge to M70. This is a small fix which may improve performance significantly on some WebGL content.
,
Sep 13
This bug requires manual review: M70 has already been promoted to the beta branch, so this requires manual review Please contact the milestone owner if you have questions.

Hi there, I'd like to understand what's going on here. Is this a MBP 2014 only issue? Pretty much every WebGL thing I've ever created is now running janky on my machine in Chrome, even in Canary. I recently found out about "Quartz Debug", an app that's an extra download for XCode you can find in the Apple Developer site (https://developer.apple.com/download/more/) as part of "Additional Tools for XCode 10.1" Running it under Window->Frame Meter is a frame rate meter showing the OS level framerate. If I run the Aquarium with default settings in Safari it's a solid 60fps. In Firefox it's a solid 60fps. Chrome Canary it runs at 52fps but sometimes mossies up to 56fps then falls back to 52fps. Worse, it's intermittent at least in stable. Sometimes I run the aquarium in stable I get 52-56fps in Chrome STABLE. Other times I get 60fps One other huge issue, and this has always been true with Chrome (no idea about Safari/FF), JS FPS meters often show 60fps but I can see the jank so I know it's not 60fps. Using Quartz Debug with stable when the issue is happening I see the aquarium thinks it's running at 60fps but Quartz Debug shows 51-52fps. I wonder if that means Chrome is swapping buffers too late so that frames are being generated and maybe even submitted to the OS at an average of 60fps (so JS things frames per second is 60) but some how the OS is not showing all the frames and so that's why I see the jank. Please consider reopening this (or start a new issue)?

Just checking but the Chrome Dev Tools FPS Meter also has the same issue. It thinks Chrome is getting 60fps but Quartz Debug shows otherwise
,
Nov 5
Could it be that since FlushForDriverCrashWorkaround is still enabled for compositing, it's affecting the compositing performance for WebGL, even though the WebGL content itself is still okay?
,

Please either move the discussion to Issue 888536 or open a new bug and let's block it on this one. Per https://bugs.chromium.org/p/chromium/issues/detail?id=888536#c20 I can't reproduce this reported regression. Please test with a fresh --user-data-dir and get rid of any themes, etc. applied to Chrome. I gather that they can induce performance regressions. |
