HD Graphics 3000 and HTML5 (direct2d) GPU acceleration

idata — Mon, 21 May 2012 18:14:20 GMT

There is as example this test:

http://ie.microsoft.com/testdrive/Performance/SpeedReading/Default.html http://ie.microsoft.com/testdrive/Performance/SpeedReading/Default.html

for testing html5 GPU acceleration. There are also other test but the thing is, on my laptop with an i7-2620m performance is extremely poor.

Also tried with newest drivers from OEM and Intel and different browsers. The results are the same:

Around 480 sec.

My desktop with a Radeon 5850 takes 7 seconds, other people with hardware worse than a HD 3000 also take a lot less than 480 sec.

My question is if anyone can repeat my results and determine that this is in fact a driver issue or just a very weak area of HD 3000 Graphics?

thanks!

With HD4000 graphics 6 seconds, this is using FireFox, and 7 seconds with IE.

Was your laptop connected to the mains? Are the performance settings on Maximum?

It's clearly not the 3000 (i5-2500k): 6 seconds here (IE10 in W8). I wonder which browser he was using?

FF12 and its a lenovo x220 with i7-2620m.

Actually the first run was unplugged but had the same thought and tried plugged in but withthe same resul. Will try to play with power settings later but I doubt it will have such a huge impact? 480 sec to like 10 sec? I doubt gpu clocks down so much.

You see this in IE9 too (not that a modern FF should have a problem, but this would eliminate some kind of browser configuration issue)?

Yes, same in IE9. Also when I disable direct2d in firefox, it get a lot slower than even now. So the GPU does seem to be doing something.

Ok, was the Power settings. They were moderate too when plugged in. setting everything to maximum performance:

Test completes in 6 sec
