I'm using v1.0.7 but had a similar problem with 1.0.6. It's currently not showing in Horizon Zero Dawn. But I had the same problem in SAO Alicization Lycoris. I did get 1.0.6 to show in Dark Souls 3. Is this possibly a DX12 issue?

Additionally I'm on the Windows insider program developer channel so that might be it as well? I'm having a similar problem in that RivaTuner isn't hooking properly so I switched to precision.

I can run the graphs on a second monitor but I can't figure out how to detach them? The X1 window is quite small so if possible I would like to detach the graphs like you can with Afterburner? 
 
Thanks 

Doesn't look like you can detach the graphs.

Thanks, I did get the OSD to display a few time. It seems I have to start it after the game is running and on the same monitor. But I'm not certain, needs more testing.
