So today i found the beutiful plugin, but upon reading the forums looks like my prefomance is not actually that good.
It looks like i have the same problem Vogelforscher had. When encoding using suggested settings(gpu=0 preset=slow qp=15 rc=constqp) i also get around 190 in AME and 200fps in premiere. Disabling CUDA does nothing, and disabling hardware decode makes premiere(or AME) unusable. Cpu usage peaks at 85, GPU around 50%.
I am using i7 8750H(6 core @3.9), 16 GB of Ram, GTX 1060(shouldn't matter, right?). Rendering and reading from my only SSD in the system(should not be the bottleneck).
