I never used vseditor, but I suspect it could slow things down.

RX 480 8GB (1330MHz / 2000MHz) ~1,29 FPS with 90-100% GPU Load.

script.vpy

Code:

import vapoursynth as vs
core = vs.get_core()

clip = core.lsmas.LWLibavSource("Sample.mkv", format="YUV420P8")
# 1920x1080 clip from a Blu-ray.

clip = core.knlm.KNLMeansCL(clip, d=3, a=6, channels="Y",  device_type = "GPU")
clip = core.knlm.KNLMeansCL(clip, d=3, a=6, channels="UV", device_type = "GPU")

clip.set_output()

launcher.bat

Code:

vspipe script.vpy NUL -p

PS. Furthermore, there is the possibility LWLibavSource has decoding problems in that particular situation.
You should use a blank clip rather:

Code:

core.std.BlankClip(width=1920, height=1080, format=vs.YUV420P8, length=1000)
