OK, I'm ripping DVDs to mkv in order to get the best out of Red October HQ. The filter graph shows that LAV CUVID is in use as the decoder, and madVR the renderer.
If madVR runs in windowed mode I get bad stutter, in exclusive mode all is fine. Using the onscreen display in madVR I see the same info in both modes, nothing significant changes. Of note is:
decoder queue 7-8/8
upload queue 7-8/8
render queue 7-8/8
back buffer queue 2-3/3
Doesn't this indicate something is underpowered?
The GPU, (GT440 DDR3) shows in GPU-Z as only using a few percent of its capability. The CPU (Core 2 Duo E7300) according to system monitor is running at an average of about 50%. I thought LAV CUVID was supposed to ease the CPU load?
Nvidia driver is recent - updated about 3-4 weeks ago. JRiver version is whatever was pushed out about 3 days ago.
