Dear Joris, Thank you for your proposal. For people that have the same issue, I have some updates. I've installed OSX Sierra (clean install), updated to 10.12.2 (16C67) with last Nvidia Web Driver 367.15.10.25f01.

Thank you for your reply

I think I've found temporary solution for this issue. I've tested wirecast's virtual camera out with full HD resolution as a source in resolume (Capturing 1080i50 in wirecast and sending it to virtual camera out). Works on 60fps without any fps drop. I didn't tested latency. So I think that somethin...
