Now THAT's confusing.
Strange. Did you check the GPU load and temperature (e.g. using GPU-Z)? Is the speed limited by the GPU or by the bus transfers/memory access? Are you using HDD or SSD? Virus scanner interference, or some other background process interfering?
What I noticed here (NVEncC x264 1050Ti) is an initial speed increase during the first few (say 10) seconds which then settles to a steady value.
