It works though (thanks) but performance is horrible, got dropped frames now.

Try going back to DXVA2 copy-back. Does it get any better? If so, forget about D3D11 as it's unnecessary and native mode doesn't work for you.
There may be a bottleneck with your GPU (only 8 lanes) combined with a lack of PCIe express bandwidth (v2.0 or lower) in copy-back mode. I've run into one other user with this problem. I don't know how he installed his graphics card. He may have installed it in a x4 slot. Native and copy-back shouldn't have radically different performance.
