I've got Vostro 3550 that I bought to improve my 3D entertainment. The problem is that I feel like I would have bought a computer from 1999 not from 2011. It looks like graphics switching doesn't work at all. There is a proof:
Cinebench OpenGL ratio is almost the same on ATI and on Intel Graphics (on Intel it's even better). What can I do? Driver is in version:8.811.1.5000.

Solved! Go to Solution.
I recently bought a Vostro 3350 with a Radeon 6470M and found that OpenGL applications don't seem to be (currently) supported by the switchable drivers at all.
After some investigation I found this fine print on the AMD homepage for switchable graphics: "...full enablement of all discrete graphics video and display features may not be supported on all systems (e.g. OpenGL applications will run on the integrated GPU or the APU as the case may be)." - "As the case may be"?
This is completely ridiculous, of course. I really hope that this will be resolved soon in an upcoming driver release.
That explains all, but it doesn't mean that I should say "Oh, OK, so everything is clear now, let's come along with that". I didn't check the page about switching technology, but about AMD HD 6630M and there is very strict information that OpenGL is supported without any note that on switchable graphics it may not be. I really don't care about graphic switching - there couldn't be that function for me at all especially that it makes my GPU out of important functions...
I've written to support about the state of the AMD driver and just received a trivial response with the driver download locations. They also said I may try to install the regular AMD drivers (which I already did) but AMD explicitly says on their download page that switchable graphics on Intel chipsets is not supported by their drivers. So it's clearly Dell's responsibility to offer new drivers.
Well, I sent them links that you've put here, with an explanation that I don't agree with AMD argumentation that on switchable drivers some features like OpenGL doesn't work. When I bought this notebook Dell didn't write in specification: Graphic Card: AMD Switchable Card. They wrote there is AMD Radeon HD6630M so I was looking for specification of this card. I found that there is OpenGL 4.1 support. If my card supports it, I want to have drivers working with it, or I want to have a choice to turn off this completely unnecessary Intel HD in BIOS.
Just bought Vostro 3550. It's a great machine, but had I know that having both Intel and AMD graphics adapters would be so troublesome and no way to enable only ATI one in BIOS settings, I would've searched for an alternative product.
Also, Dell's own graphics driver updates are broken. Here's what I did today:
I went to my Dell support page, downloaded Intel HD Graphics driver 220.127.116.111, A03, which is an upgrade to the factory supplied driver that I had, and installed it.
First when I started driver setup it complained that currently installed drivers are newer, including Intel audio drivers, but as I have compared file versions of the installed files and files in the update and found that graphics drivers are definitely more recent in the update, I dismissed this.
I went ahead anyway and installed the update. Now after the reboot the ATI graphics adapter was gone, device manager did not have it listed (there was just some kind of a brandless standard adapter instead, I recall), and I had to reinstall ATI drivers after updating the Intel ones... And now, I do not know where to put finger on it, but switchable graphics settings have been acting kinda funky... few times I have not been able to add new programs by browsing to them, and other times I have been able to do so.
BTW anyone eloquent and persuasive up to starting a thread on
so that Dell would hopefully notice our problems and act on them?
Here in Brazil the Vostro 3450 has the same problem. The switchable graphics funcionaem not all applications. You will need a BIOS update to be able to choose which video to use. DELL question is when will pay attention to the problem.

I wanted to step in and post that engineering is aware of the problem. I don't have any specific dates but engineering I believe is working on a BIOS update that may help with problems running Open GL programs. Once I find out anything more I will post here.
