Hardware acceleration

By Tommy A. Olsentoman. Wednesday, October 12, 2011 12:46:26 PM

, , , ,

Hardware acceleration allows Opera to offload graphics rendering from the processor (CPU) to the graphics card (GPU). This makes graphics intensive operations such as animations faster. The ability to render with the GPU opens up the ability to render WebGL as well. WebGL allows programmers to write 3D games and fancy-looking demos for you to play with.


The way Opera has implemented hardware acceleration is a bit different from the way many other browsers have implemented it. We render absolutely everything using the GPU when possible. All of the user interface, and all of the web-page, and WebGL.

Performance
Currently our implementation in the Alpha version makes the most intensive things a lot faster, while some things are still not as fast as the optimized software backend. We are aware of what is causing this, and are working to improve the performance significantly.

One thing we have done to improve performance is to limit how often we draw to that of modern monitors. This means that some tests may report a lower frame-rate, while in fact the actual rendering is a lot faster, since both the CPU and the GPU won't be busy trying to render things that can't be displayed anyway.

Supported graphics cards
This Alpha release only supports OpenGL. DirectX 9/10 support on Windows is work in progress. Like other browsers, we are blocking troublesome graphics cards and drivers. We control which are blocked with blocklists, which are separate per platform and back-end, and is located in <install-dir>\extra\.

When a card or driver is blocked, Opera falls back to using software rendering. You can check the current status on your machine by opening opera:gpu. If the page says "Vega backend Software", try to upgrade your driver. Note that some cards are not supported by the vendor anymore, and these may still be blocked even if you have the latest driver for that card.

Testing
If you see a bug, try to turn off hardware acceleration by setting opera:config#UserPrefs|EnableHardwareAcceleration to 0, restart Opera, and see if the bug is still there. Not surprisingly, this turns off hardware acceleration, so remember to set the preference back to 1 after testing to enable hardware acceleration again (0=off, 1=auto, 2=force on).

Some cards will get WebGL disabled due to problems with the card or driver. If you're confident that it will work, you can force this on, set opera:config#UserPrefs|EnableWebGL to 2 (0=off, 1=auto, 2=force on). Even if these settings can be changed, we advise you to change them only for testing purposes.

Please provide your feedback on hardware acceleration in this blog post. Supply steps to reproduce, and the following information:
  • Operating system
  • Graphics card make/model
  • Graphics card driver/version


Comments that do not relate to hardware acceleration will be deleted.

Just a question out of interest. Does it work with the opensource Linux graphics drivers (Mesa/Gallium3D based)? As I think that would be a first (AFAIK both Firefox and Chrome can't do it). But then again, it took you more than four years (after the first announcement on the core blog) to get to this point and you still don't have DirectX support wink

FitzTN Thursday, October 13, 2011 7:32:13 AM

Hello,
I installed Opera alpha and it was terribly slow and taking 600 - 700 MB of RAM with only 3-4 open tabs. By disabling hardware acceleration everything went back to "normal" and functioning properly.
My computer is a HP 8710p, graphic card is nVidia Quadro NVS320M with drivers 275.33. OS is Windows 7 professional x64.

Robert,

HWA/webgl works for me on Intel Linux:
GL_RENDERER: Mesa DRI Intel(R) Ironlake Mobile
GL_VERSION: 2.1 Mesa 7.10.3

Would be nice to have some information about where it's supposed to be working though.

1. doesn't work with AMD Catalyst 11.10 preview driver 2 (driver reset)
link to driver: http://support.amd.com/us/kbarticles/Pages/GPU122AMDCat1110PreDriverV2.aspx
(tested on windows vista x64 SP2 with Radeon hd6870)

-> to get it working you need the atioglxx.dll (AMD OpenGL driver) from Catalyst 11.9 (latest official stable driver) and copy it to the Opera directory

2. with Catalyst 11.9 you get black menus etc. see:

Ram usage is quite high... currently 334mb which is about 100ish higher than normal. however this is no real issue as i have plenty of ram.

performance is... decent. it stutters here and there, and seems to be capping out at 58fps rather than 60fps which does feel a tad... off. (thats with a gtx580 card).

further more, a LARGE annoyance. opera is now fully and amazingly blurry everywhere due to 16x CSAA being applied as i have this enabled in the nvidia control panel for games. would be nice to have opera exempt from the AA unless this is simply not possible. seems a bit of a pain to setup a custom profile for opera to disable AA when a lot of people will experience this.

BrookeChookWoods Thursday, October 13, 2011 7:40:05 AM

actually now that ive said that, i just disabled AA and set it to forced off. closed opera and reopened it, yet im still massively blurry everywhere. anyone else getting this?

If you force it on you are using it in an unsupported mode and hence you will see more issues.

My computer has Optimus. Opera defaults to the integrated graphics, which is not supported (HD Graphics 3000). I can switch is to the Nvidia card, but most people probably won't know to do this.

MacBook Pro MC725 with OS X Lion 10.7.2, build 11C74. Opera now always triggers more powerful Radeon HD6750M GPU immediately after startup, even without any WebGL content on a page. Safari manages to run on integrated Intel HD3000 GPU. The same problem is found in Google Chrome. Probably this link will be useful for you: http://crbug.com/88788

I consider it as a great issue, as it can easily eat away some hours of battery life.

About hardware acceleration itself, it seems to be working in general. After some time spent in HelloRacer demo, RAM usage is about 600Mb, drops to 300Mb after closing the tab. CPU usage is about 50% of one core.

Horribly, horribly slow. While opera:gpu tells that software renderer is used, opera is many times slower than previous snapshot.

And weird thing is that -nohwaccel helps. While renderer is still software.

Ashus Thursday, October 13, 2011 9:15:48 AM

Higher CPU usage on scrolling, stuttering (the GPU is not clocked higher at all times, how do other browsers handle responsivity?), MEM usage OK.
Main menu (gui) is a bit more blurred than before (ClearType), but still well readable. Much better than early GPU accellerated versions.

When you say DirectX support, will that mean only Direct3D, or also the other API, like DirectWrite?

1-Some redraw issues here, when scrolling page with Flash elemtns (youtube etc), redraw issues occurs on tab bar + address bar!

2- Some elements are not drawn correctly, eg: On Html5test.com some headings are not drawn correctly (eg. Parsing rules

3-FPS is not maintained at 60hz, it shows between 57,58 but performance is good.

'DirectX 9/10 support on Windows is work in progress.'

I was just about to say Thak you to Opera until I saw the above line. Because now I have a lot of confusion. With DirectX 11 being the latest version, why is Opera only supporting DirectX 9 and 10. I know there must be a valid reason, Opera won't do anything wrong, but I want to know why?

I can't turn HA off. Am I missing something obvious?

http://i.imgur.com/WogJI.jpg

http://i.imgur.com/L1VZ4.jpg (I made both screenshots AFTER "disabling" HA)

1) I saved setting in config (yes I've seen the message, that told me that some setting may not work without restart and that something was saved!!!)

2) I restarted opera next few times.

3) I refreshed opera:gpu site using f5.

4) I made new fresh usb install to completely new folder.

5) I repeated 1-3 steps few times with fresh opera.

Still OpenGL showed in opera:gpu as a backend, but not in opera:config (as shown on pictures). That is even in fresh usb instance. I suspect that HA may be on all time. Because I did the same on my desktop PC with the same result. I must add that ONLY on my desktop pc Opera was a bit blurry (http://i.imgur.com/JGE7s.jpg) before and after "disabling" HA, so I suspect HA is on all the time. I also have to add that today I updated Flash Player from this site: http://get.adobe.com/pl/flashplayer/ to Adobe Flash Player 11.0.1.152. My question is whether the info at opera:gpu is false or true? And if true, I can say that I'm unable to disable HA to test any issue that I suspect is caused by HA.

First issue was mentioned before, was about blurry opera on my desktop pc. (there is another issue, but I will report it in other blog post about opera 12 alpha)

Second issue is on my laptop. http://www.gtfogaming.co.uk/ banner overlaps (kinda, tabs disappear or are white, it's hard to say exactly) the parts of opera user interface that are above that banner while scrolling down. I can't test it w/o HA for the reasons I already mentioned.

MSI CX720 i3 with Optimus on W7-64
nVidia 310M + Intel HD

Optimus choose Intel HD for Opera which is not currently supported so Opera falls back to software rendering. GPU acceleration forks fine After manually selecting nVidia but rise in overall temperature is significant so i decided to wait for Intel HD support. Low temperature and longer battery life are more significant to me at the moment.

Is there possibility that Opera can utilize Optimus and select appropriate graphic card depending on current activity?

You really don't want Opera to turn on the dedicated GPU. It will consume lots more power than the integrated GPU does. For some simple 2D rendering the integrated GPU should be enough. Opera should just properly support the integrated Intel GPU, and the switching of GPUs (when using heavy WebGL stuff, but don't know if Windows doesn't do this automatic already)

Albert Raccoonalbertraccoon Thursday, October 13, 2011 10:51:30 AM

It seems HWA can't fully load the graphic card.
For example, when executing the PsychedelicBrowsing test with no other graphic load, I get ~900rpm. However, when loading the graphic card with the Folding@Home GPU client, I get ~3000rpm.

It is not Opera who gets to decide which graphics card to use. Like you said, YOU can choose which GPU to use. Where do you do this? The nvidia control panel. So your drivers decide which application defaults to what.

I can't even see Opera's window. Only artifacts. Sometimes I saw a form of opera:config page and somehow managed to disable HWA. Will Intel cards going to be disabled?

on Arch 64. Performance with HWA and WebGL is very bad, high cpu load.
google's "evolution of the web" demo produces rendering glitches with HWA.
