1099354 - Very slow 3D graphics performance on machines with AMD+Intel GPUs (switchable graphics)

Status: REOPENED

(Core :: Graphics, defect, P3)

Description

[raff]

User Agent: Mozilla/5.0 (Windows NT 6.3; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/38.0.2125.111 Safari/537.36

Steps to reproduce:

Start FireFox, visit http://threejs.org/examples/#webgl_animation_cloth

Using I5 Laptop with AMD 8800M/Intel 4000 switchable graphics. Even on Intel should run at 60 FPS.


Actual results:

ThreeJS examples run very slowly,typically 20 FPS compared to 60 FPS on Chrome/IE11 and previous versions of FireFox


Expected results:

Performance should be around 60FPS as before.

Please provide the graphics section of about:support . Have you tried updating your drivers?

It sounds like we used to support HWA on your chipset and now dropped it because of driver/GPU issues. Checking the drivers are up-to-date would be the first step to figuring this out.

Resolving this as INCOMPLETE due to lack of information.

@raff, please reopen this bug report and provide the information requested in comment 1 if you're still able to reproduce this in the latest Firefox version.

Tried this page on two different laptops:

http://threejs.org/examples/#webgl_performance

Chrome gets 30-45 FPS, FireFox 40.0.3 10-15 FPS

Seems better than it was on previous versions of FireFox (for some ThreeJS examples), but still poor compared to Chrome.

Here's the video info dump of one of the laptops:

-> milan?

Comment 5

[Mayank Bansal]

depends on bug 975132 ?

Comment 6

[u279076]

There's a couple systems in Toronto with the same Intel GPU:
https://wiki.mozilla.org/QA/Platform/Graphics/Inventory#Generation_7

Could we give those a shot at finding the regression window, if this is indeed a regression?

Comment 7

[Milan Sreckovic [:milan] (needinfo for best results)]

When was it better?  The comments indicate that 40 is better than before, and that version from comment 0 is even better.

Comment 8

[Benoit Girard (:BenWa)]

I get 60 FPS @ http://threejs.org/examples/#webgl_performance at 4K on my MBP. Looking into the windows performance.

Comment 9

[Benoit Girard (:BenWa)]

I get 40 FPS on windows with Chrome & Firefox (release or nightly). ~20 FPS with Edge.

Quadra 600, D3D11 + D2D 1.1

Comment 10

[Benoit Girard (:BenWa)]

Alright, I can reproduce on a somewhat similar machine:
Firefox Release or Nightly is getting 8 FPS, Chrome is getting 30 FPS

Machine:
GCN 1.0 - Oland	AMD Radeon HD 8570M	0x0166	Intel HD Graphics 4000	Thinkpad G500

Comment 11

[Benoit Girard (:BenWa)]

So we're disabling surface sharing on this configuration of 'Unexpected Intel/AMD dual-GPU setup'. This halves our FPS rate. By setting layers.acceleration.force-enabled;true I get 15 FPS. Still half of chrome.
The time is spent in uniform updates.

Comment 12

[Benoit Girard (:BenWa)]

Bug 1207170 will double the performance (8 FPS -> 16 FPS).

The rest is CPU Bound because of the draw calls. On chrome it's done in the GPU process so it gets a bit more time to run because it doesn't need to run JS. But I'm not sure why it would get double the frame rate. I'd expect it to be more like 20-50% faster, not 100% faster.

[Benoit Girard (:BenWa)]

Sorry I meant bug 1097321.

Comment 14

[fireattack [:fireattack]]

JFYI, the support of AMD+Intel GPUs (switchable graphics) literally doesn't exist on my computer.

Setup: AMD Radeon HD7400M + Intel HD Graphics 3000 + Win 10 x64 + Firefox beta (43) x64
I used the modified driver because AMD's official one locks browsers to energy saving GPU.
I set both firefox.exe and plugin-container.exe to "high performance" (AMD GPU).

After that, I can't even start my main profile, NOR profiler: they both can not even render the user interface (totally black/white).

To be honest I consider this is a crucial bug that needs to be fixed ASAP..

Comment 15

[Benoit Girard (:BenWa)]

What you're describing is a different issue. Can you file another bug for it?

I filed that with bug 1225285; However I have another problem that may related to this bug: when I check about:support, I can never see my AMD GPU, only intel's. Is that normal? I filed another bug about that anyway: Bug 1225284

[Sergey I.]

Just my 5 cents..

Firefox 43.0
Gentoo Linux, AMD HD7970M+Intel, fglrx driver 15.12. X server set up to always use ATI card.

For http://threejs.org/examples/#webgl_performance
Chrome:  33 FPS
Firefox: 20 FPS

For http://threejs.org/examples/#webgl_animation_cloth
Chrome:  60 FPS
Firefox: 37 FPS

Comment 18

[Sergey I.]

Just tested on Intel hd4000

For http://threejs.org/examples/#webgl_performance
Chrome:  17 FPS
Firefox: 15 FPS

For http://threejs.org/examples/#webgl_animation_cloth
Chrome:  60 FPS
Firefox: 52 FPS

Comment 19

[Pasi Keinanen]

This is NOT limited to AMD CPUs and Intel GPUS. Just FYI. My data on intel Xeon 6-core 4.2GHz w/ nVidia Geforce GTX 1080. Firefox 49.0.2 (release channel):


For http://threejs.org/examples/#webgl_performance
Chrome:  steady 59-61 FPS
Firefox: max 21 FPS

For http://threejs.org/examples/#webgl_animation_cloth
Chrome:  steady 60 FPS
Firefox: steady 59 FPS

Just FYI.

[Milan Sreckovic [:milan] (needinfo for best results)]

There are a few issues in this bug for sure.  Dual systems vs. different performance on different hardware.  And probably a few more.  We could treat this under the "webgl performance compared to chrome".

Comment 21

[Milan Sreckovic [:milan] (needinfo for best results)]

A WebGL performance issue that is visible across all vendors.  Not sure it's a kind of thing that we want to track as platform-rel.
