I've got HP 250G laptop with Radeon 7450m dedicated card and HD Graphics 4000 integrated one. The specs both cards are support OpenCL, but OpenCL software are crashing on my system: caps viewer and vegas pro 12 does not start, gpu-z outputs "intel opencl driver bug". Drivers seems to be ok, dual graphics works fine. I've downloaded catalyst mobility 12.8 from hp portal. HD Graphics 4000 was included into this package, AMD OpenCL driver too.
