re the original post and slow conversion times in DVDFab 10. I'm not sure if this helps or will just lead to more debate.
When DVDFab was released it generally took about 65% longer to rip and convert than the same process/settings in DVDFab 9.3.2.1.
When the 64bit version was released it was slightly slower than the 32 bit version of DVDFab10.
Due to the unexplained slowness in DVDFab 10 I have continued to use 9.3.2.1. My preference is 'Software' so all GPUs disabled. The 'Software' setting is generally slower but provides much better and consistent results when compressing video, than does CUDA and other acceleration options.
My P/C is i7, Windows 7 64bit, 16Gb RAM and Nvidia GTX650. As far as I can determine all drivers are updated.
More recent tests show that DVDFab 10.0.6.5 (64bit) is now even slower. For example:
Rip a 2D Blu-ray to MP4 using 9.3.2.1 (standard quality, 1 pass, all GPUs disabled) = 2 Hours, 42 Min (Output size 4,311,007KB)
Rip same Blu-ray with same settings on same P/C using 10.0.6.5 (64) = 4 Hours, 56 Min (Output size 4,307,536KB)
The 32bit version of DVDFab10 is even slower....around double the time for some processes.
Granted, DVDFab 10 has more functionally but I have been unable to understand why this results in 10.0.6.5 (64) taking 83% longer to process rips and conversions. Similar results around 83% longer for 3D Rips, DVD Rips and .mkv to .MP4 conversions.
I know CUDA is faster but the purpose of the exercise is to show how slow DVDFab10 is compared to the DVDFab9.3.2.1 and hopefully lead to some improvement in the processing times.
I have the log files for the two tests above if required or can provide more info if necessary.
