  • CPU/GPU DVDFab CUDA support status

    ~PLEASE NOTE~

    This post has been extensively updated based on further development work and feedback from users. Please check all the content again to obtain optimum performance with DVDFab.
    Last verified: 9 December 2014




    The following information was supplied by DVDFab developers and the QA Team to clarify the situation regarding recent problems with nvidia drivers.

    Background

    Recent evolution of nvidia hardware (Kepler based devices) has also brought changes to the drivers that nvidia supplies. Unfortunately, nvidia has chosen with recent drivers not to support the CUDA video encoding function on their GPUs with CUDA capability below 3.0 (see this for a list) Nvidia drivers now support only their new NVENC technology, which much hardware does not support. This makes the situation apply to many DVDFab users. To regain some of the CUDA advantage, DVDFab now (v9.1.6.3 and later) supports CUDA for decoding and the new NVENC for encoding using the latest nvidia driver (340.52 as this is written) on devices with CUDA capability of 3.0 or higher. Whether this is the optimum solution for you depends on how you use DVDFab, as explained below.

    Other Aspects

    The instability issues with the 337.88 and 340.52 drivers have been overcome for DVDFab versions of 9.1.6.3 and later, so if your nvidia device has a CUDA capability of 3.0 or better (see list linked below), you can use these drivers now, but should choose between them carefully depending on usage pattern: for Full Disc with compression in Blu-ray Copy, you will get better performance in most cases using the 337.88 or earlier driver with CUDA decode and encode. For Main Movie compression or tasks using the Ripper or Converter modules, use the newer 340.52 driver and CUDA decode with NVENC encoding, which is now fully supported by DVDFab for these (3.0-5.0 CUDA cap) devices. It is a shortcoming in the driver itself (a weakness in handling the many small m2ts files common in Full Disc mode) not in DVDFab that is the basis for this recommendation.


    Earlier nvidia Devices

    What about the legacy (non-Kepler) devices that many of us still have? DVDFab has not forgotten. If your device has CUDA capability below 3.0, the 340.52 driver does not support encoding on your device and you must choose to use the new (340.52) driver with decoding only (will be slower) or the older (337.88 or prior) driver to continue using CUDA for decode and encode.


    Alternatives/Workarounds

    You may wish to consider using Intel QuickSync (IQS) if your CPU and motherboard chipset support it. See the link below for more information.

    Summary of Recommendations
    • If you primarily use your GPU for compressing Full Disc BD content, use a pre-Kepler driver (337.88 or prior) to continue using CUDA for decoding and encoding.
      • DVDFab v9.1.6.3 or later and a CUDA 3.0 or higher rated GPU required.
    • If you primarily use your GPU for Main Movie or with the Ripper or Converter modules, install the latest (340.52) driver and use CUDA decoding and NVENC for encoding.
      • DVDFab v9.1.6.3 or later and CUDA 3.0 or higher rated GPU required.
    • If your GPU is rated below 3.0, you should not update to any of the Kepler drivers (340.52 or later) if you wish to continue using the GPU for encoding.
      • Consider using the GPU for only one task and using the Software setting for the other, especially if you have an i7 CPU and a GPU with a CUDA cap rating of 2.1 or below. Intel QuickSync (IQS) is another possible alternative if your PC supports it.


    Thanks for the feedback provided so far.

    Thank you for the update signals. I'm using a GTX 660 and have rolled back to the 335.23 driver until this issue is resolved.

      Thank you for update status. I did'nt have an integrated GPU in my Intel Core i7 2,4Ghz Notebook. Only the dedicated Geforce GTX780M.

      Without support of Geforce Encoding, still, the Encoding time increase from 20-25 Minutes up to now to 40-60 Minutes. In the Same optical Quality.

      I've rolled back to the Geforce 335.23 Drivers to use GPU Encoding, but many games needed newer Geforce Drivers.

      I hope this issue will the fixed as soon as possible.

        Thanks for this should include Wilson.Wang of the QA Team in Beijing, it was his idea, and a good one, this subject needed a detailed explanation. I hope it is all fixed soon as well, but it is complicated to some degree by the presence of a 3rd party (nvidia).

        Don't overlook the option to use the 340.52 driver if you need it for gaming, you can use it for the decode part of video compression, which may still produce pretty good times if you have an i7 (and good fans) .

          I would like to know if Wilson Wang or any of the DVDFab team might be able to give us an estimate as to how long it will take to resolve this issue so that full Cuda functionality will work with the new NVIDIA drivers.

            You have got to be kidding. "How long is a piece of string?" comes to mind.

              It is ready now, please install v9.1.6.2. Beta and the 340.52 driver and post the results here, feedback is needed. Devices below CUDA capability 3.0 are not supported yet.

                i installed dvdfab 9.1.6.2 beta and ripped a few dvds. It works very well !!!. Can someone Test it with Bluray Ripping ? Have no time, go to work. At this point, very goog work.Thanks very much.

                  DVDFab 9.1.6.1 gave me a few errors and made it crash everytime especially when ripping directly from disc + when CUDA was selected. Worked okay with Intel Quick Sync.

                  DVDFab 9.1.6.2 works perfectly well...and no issues replicated.

                  WELDONE DVDFAB TEAM. GREAT JOB!!!

                    Thanks for the feedback so far, I think a few more reports would be appreciated by the developers, especially if you experienced any problems.

                      Cuda a lot faster for me now with V9.1.6.2

                      With all setting to CUDA V9.1.6.2 is a lot faster for me now.
                      Great improvement from V9.1.6.1 on my system.

                        Full Disc Issue

                        Hi

                        When I select main movie it works fine but if I select full disc it starts off ok but then grinds to ha halt and I have to cancel.

                        I'll post the internal log below as it's too big to fit in one post.

                            You can cut the current log file in notepad and then paste here.
                            Or attach the file directly by click Attach icon.

                              Hi

                              I tried to paste into my original post but I got a message to say it was too large. I noticed you could attach files so I attached a zip file with it and a screen shot and posted it below my original post. I've attached it again for reference.

                              Sorry for any confusion.
