There is default option "High Performance" but it still works with Intel HD Graphic too.

I downloaded and installed these drivers http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS013670 , but it still seems that I have old drivers , because of this Date of release http://goo.gl/lQ9aO

@Recursion: But you have E420s with updated BIOS, right?

Betreff: E420s switchable graphics with opengl

OK, I've just downloaded and installed the latest video card driver.

 

How do I get the latest BIOS to enable switching through CCC?

Re: topic

Yes. Probably newer version of drivers which solves every problem.  Latest Ideapads also have them with no problems

This whole thing is solved for a long time. Only missing thing is to modify these drivers for our Edge notebooks.

I wonder if it is so big problem for lenovo that takes so long.  I get it, Idepads are a little different,  but  edge 420s ?!   It is almost same notebook.

@JameZ:

 

I have installed the new driver package (which updated both the Radeon and Intel drivers) on my Thinkpad Edge E520 w/o problems, but all applications that use OpenGL still run exclusively on the Intel HD 3000 GMA, regardless of high performance settings in Catalyst Control Center.

 

The new driver package updated the Intel driver to version 8.15.10.2476, which shows some improvements, yet I still get a system crash from ig4icd32.dll (the Intel driver's OpenGL module) during the startup of the OpenGL based game Rage.

 

As with the old driver package, I can get Google Earth to run in OpenGL mode, but only on the Intel GMA.

 

Thus the update did not solve the problem for me, i.e. switching to the discrete GPU remains impossible with OpenGL applications.

Re: E420s switchable graphics with opengl

Dear JamesZ.

The problem is not only with the E420s but also with all other laptops with 6630m like my E520. The drivers you posted didn't fix anything for me. Rage does not work because it still detects only the Intel card which doesn't have OpenGL extensions that the AMD card has.
