We currently need to framelock a D3D9 application between different computers (synced by S400) for a massive video wall type scenario. We use multiple FirePro W8100 cards and S400.
How can we synchronize buffer swaps and join groups while using the D3D API?
We'll later be moving to d3d11 and will need it there too. Looking at the WGL sample, it should be pretty easy to do the same with D3D.
