Hi Alberto,

for NVidia and AMD graphics cards, we declare 2 public variables at 
global scope to force using GPU at run-time (even if there is no 
existing application profile).


extern "C" {

     /// Declare this variable in public to enable the NVidia side of 
Optimus - 
http://developer.download.nvidia.com/devzone/devcenter/gamegraphics/files/OptimusRenderingPolicies.pdf
     __declspec(dllexport) int NvOptimusEnablement = 1;

     /// Declare this variable in public to enable the AMD side of AMD 
Switchable Graphics (13.35 driver or newer needed) - 
http://devgurus.amd.com/thread/169965
     __declspec(dllexport) int AmdPowerXpressRequestHighPerformance = 1;

}

Regards,

Florent

That is what I tried, but it was not obvious to me.  Apparently our
client got it to work, nevertheless, so I will ask them how they did it
for reference.

That solution would be indeed nice to know, but I also had not luck
finding it.

Nevertheless, apparently our client got it to work tinkering with the
driver settings, so I will resume this search at a later date.

Thank you for the insight!

I owned laptop with same configuration and obviously the Radeon driver
software kit (or how it is called) comes with an app where you select the
card per app. You select your app in this Radeon app and it will run on the
selected device

I believe I was previously told that there are some secret C symbols
wherein if you create a variable of a particular name, it acts as a hint to
the driver to trigger particular behavior.

I can't at the moment find the names of the symbols or what they do, but
I'll look around. Maybe you can find it before I do based on that knowledge.

[osg-users] Selecting a GPU to be used in a dual-GPU laptop

2018-10-18 Thread Alberto Luaces 
Hi,

some client owns a laptop with a dual GPU system —the typical integrated
Intel card plus an additional Radeon 530 one into a windows10 system.

It seems that the driver selects automatically the Radeon when using
some CAD applications, but only the integrated Intel when running our
OSG program (checked from the Program Manager window).

I heard that in some analogous nVidia systems one can set manually a
given program to run with the powerful GPU in the Control Panel, but at
least, if it were possible in the AMD drivers, it is not immediately
apparent (we didn't find how).

Does anybody have experience in this kind of Radeon systems?

Thank you!
