Thanks for the insights!

Agreed, it's a little cumbersome but afterwards you can be pretty confident in your result. Have you measured 3ms like that? Getting below 3ms with small deltas using NVENC sounds possible but considering that even with a refresh rate of 120fps there is over 8ms between two frames, 3ms does sound suspiciously low.
One last question, have you done any experiments with the video codec, due to compatibility requirements I am pretty much limited to H.264 but was wondering if there is something better for super low latency encoding?
