OpenGL and hybrid-graphic problem

**Francytopo** · 10-21-2011, 03:14 PM

Hi all,

Some months ago I bought an ASUS K53SV with Intel HD 3000 and Nvidia GT 540M graphics. While I was testing Penumbra games on it, I found out they were using the integrated card; I promptly added the .exe files in the Nvidia CP whitelist but video settings didn't change, just like the games kept running on the Intel graphic.

An excerpt from hpl.log:

Initializing Graphics Module

--------------------------------------------------------

 Init low level graphics

 Setting video mode: 800 x 600 - 32 bpp (for the record, the Intel graphic uses a stable 1366x768 res, but due to in-game unavailability it defaults to the lowest. However, here the Nvidia adapter is selected, which should use instead a 1280x720 res)

 Init Glee...OK

Actually, I figured out the problem has to be addressed to OpenGL, which uses the integrated card and makes the games to detect it, even if the preferred graphic is selected as Nvidia. I downloaded the GLEW, that comes out with this:

An excerpt from visualinfo:

Code: (Select All)

OpenGL vendor string: Intel

OpenGL renderer string: Intel(R) HD Graphics Family

OpenGL version string: 3.1.0 - Build 8.15.10.2509

My question is: is there a way to change the OpenGL graphic renderer to Nvidia?? I've Windows 7 x64 and the latest drivers for both graphics. Thanks in advance.

from the nvidia control panel. At my laptop I can also right click at every application and select with which graphics processor I want to run it with.

Yes as I said I've selected the games to run on Nvidia but nothing changes.

Make sure you have these installed:

http://www.geforce.com/Drivers/Results/38110 for nvidia
http://downloadcenter.intel.com/Detail_D...pe=Drivers for Intel

Can you right click at the game and select to run it with the nvidia card like I do?

Have you read my thread?? I said I've the latest drivers (these drivers) and YES, I can select the graphic processor to run the games with the Nvidia graphic but Penumbra keeps detecting the Intel card, even if I add the exe files in the Nvidia Control Panel or right-click at the games, most probably because the integrated is directly connected to the display. The problem is clearly OpenGL, and since there's no option in the Nvidia CP to make it recognizing the dedicated graphic, I need to know a solution that directly acts on this interface.

I don't know. Nvidia does not work like that so no idea. Either way, Penumbra can be perfectly run with the Intel HD card so no problem.
