Hi All

New to DVDFab and the forums (first post - woowho!)

Been playing with trying to get optimal performance for what I consider relatively fast hardware (from more of a benchmarking standpoint like benchmarking FPS in a game).

Using my Avatar Bluray original as the base line source file.

Thing is... Not sure what the optimal Performance is (IE. What I could be getting verse what I'm actually getting). Dug around the forums; but still a bit unsure..

Note: Currently not able to get Intel Quick Sync working atm (DVDFab crashes, stops with a error code, or just runs forever).

From my testing so far (with this machine and slower AMD x4), CUDA seems to be the best (lightning recoding on or off nets about the same overall process time)

Here are my results:

Software only: about 3.18 meg/sec and a process time of around 208 minutes
Software + Lightning Recoding: about 7.69 meg/sec and a process time of about 86 minutes
Cuda: about 8.27/MB sec and a process time of about 80 minutes
Cuda + Lightning Recording: about 8.07/MB sec and a process time of about 82 minutes

Note:

- In pure software mode, CPU Speed + number of Cores looked to be deciding factor in overall conversion times.. IE.. A AMD X4-970 3.6 GHZ CPU Processed the same BD image in about 400 minutes
- Disk I/O didn't seem to make much of a difference overall as long as as the I/O subsystem could feed enough data to DVDFab During re-encoding CPU Processing. Two exceptions were when the ISO image is being initially scanned and during the building of the final ISO image, where all available disk bandwidth was in use. (added about 25 minutes over the AMD processing)
- On a machine where the CPU is crazy fast, Disk I/O would then be more of a concern. IE. AMD - 15 minutes final ISO Build Time, i7 - 2 Minutes
- Running Source ISO, TEMP files, Final ISO on different Physical Drives (SSD) may help to tweak even more performance depending on how DVDFab processes data.

So my question to the forum is.. based on my hardware (in signature):

- is 80 minutes good?
- Anyone able to re-coding faster, if so, then any ideas as to why (IE. Faster CPU, Intel QS working, Multiple SSD, etc)
- If software (with Lightening) is close to Cuda, then is Cuda really working?
- If software (with Lightening) is close to Cuda, then which could be considered the better way for overall quality?

Any input is appreciated

Thanks

**What was done and Settings**

Image Copied to Hard drive from BluRay Media. BD50 to BD50.ISO with protection stripped (about 44 minutes and is not included in the re-encode times above)

Then down sample was performed

BluRay Copy -> Full Disc
Remove HD Audio: Enabled
BD50 -> BD25 Size 56% (39.784 -> 22.461)

CommonSetttings/General/AV Codec (this waS for Cuda without lightning)

Decode
- H.264: Cuda
- VC1: Cuda
- MPEG2: Cuda

Encode
- H.264: software + Cuda
- Lighting recoding: Not enabled

CommonSetttings/Bluray-Copy
- Enable Full Scan
- EncodingSettings: SlowSpees/HighQuailty
