I recently bought a Samsung Ativ Book 8 wich comes with the Radeon 8870 as a discrete GPU besides the internal Intel 4000 HD GPU.
If I run games the laptop switches over to the Radeon GPU just fine, but running webGL or 3d flash in chrome does not activate the discrete GPU.
( I check this with GPU-Z )
chrome://gpu does not even list it (only the Intel 4000 HD).
same issue in firefox.
I have ofcourse configured "Switchable Graphics" to run on high performance in general, and also selected all browsers to run in high performance.
The issue is the browser does not 'see' the Radeon GPU at all.
Anything that can be done? Is this a driver issue?
