I'm not aware of any particular AMD hardware limitation. A HD7970 is a
lot faster than a GTX680 in GPU rendering.
LuxRender uses hybrid rendering because the hundred of thousands of
lines of Lux code will never runs on any GPUs. For the same reason, it
very unlikely to ever see OSL in any GPU renderer.
If you want 99% of features you have on the CPU, you have to use hybrid
rendering. If you want to run at full GPUs speed, you have to accept
many limitations. LuxRender has an hybrid renderer for the first case,
and now a SLG renderer for the second.
Cheers,
David
