Quick test. Played back through vdub using a 1920x1080i mpeg2 source and compared vapoursynth SSE2 version (using version R15) and the latest avisynth version (using an avisynth script) with my Q6850 quadcore cpu & WinXP pro. Vapoursynth version runs most optimally with vs.Core(threads=5). Changing it to threads=6 didn't seem to be much better. Avisynth version worked optimally at threads=4. Vapoursynth version runs about 2-3fps faster than avisynth version.

Vapoursynth script

Code:

import vapoursynth as vs
import sys
core = vs.Core(threads=5)
core.avs.LoadPlugin(path=r'C:\dgindex\DGDecode.dll')
core.std.LoadPlugin(path=r'C:\Program Files\VapourSynth\nnedi3-testing.dll')
ret = core.avs.MPEG2Source(r'E:\mympeg2.d2v')
ret = core.nnedi3.nnedi3(clip=ret,opt=2,field=3)
last = ret

17fps-18fps

Avisynth scrpt

Code:

mpeg2source("E:\mympeg2.d2v")
nnedi3(opt=2,field=3,threads=4)

15fps-16fps
