Mag79.. Don't know if this helps in anyway but... I had noticed that the new SVP configuration (svpflow dlls, AVS+ avisynth.dll, and new avisynth script - doing nothing but loading svpflow dlls, configuring SVP and running MSMoothFps.avs) reported (via ctrl+J in MPC-BE) higher peak CPU utilization but didn't drop frames where the old version did. All libraries, folders and MPC-BE settings and such were identical excepting the Avisynth.dll, svpflow dlls and the main avisynth script for ffdshow raw video filter. As I reported in the "Running out of memory..." thread:
What I did discover while comparing AviSynth 2.6 MT to AVS+ rendering the "SONY F55 4K Blue Shanghai Zhen Wang Wei 150mbps.mp4" video was that although the CPU utilization was similar, AVS+ didn't drop frames in the most difficult sections of the video. AviSynth 2.6 MT would drop frames for me when CPU utilization topped 63% while AVS+ would hit 70% in the same section but not drop the frames that AviSynth 2.6 MT did. Perhaps I could eliminate the difference by tweaking threads in AviSynth 2.6 MT... In any case AVS+ coupled with the new SVPflow DLLs works fine as far as I'm concerned.
I retested both configurations just to make sure things were right (they were) and performance was still as reported. In addition I rendered a run of the mill 1080P/24fps file (https://vimeo.com/50855881) and noted 8-12% CPU utilization with the old SVP configuration and 13-17% CPU utilization with the new SVP configuration. GPU utilization hovered around 24% with the old version and 23% with the new one. I failed to capture average jitter readings but the new version just 'feels' smoother.
