HC3 not working, vs HC2

[bastibasti]

Thank you for pointing it out.

for the next gentoo user:

# eselect opengl list
Available OpenGL implementations:
  [1]   nvidia
  [2]   xorg-x11 *
# eselect opengl set 1
Switching to nvidia OpenGL interface... done

# eselect opencl list
Available OpenCL implementations:
  [1]   mesa *
  [2]   nvidia

# eselect opencl set 2
Switching to nvidia OpenCL interface... done


now it works. BTW significantly slower than the cuda implementation, but i guess opencl gives more compatibility.
