[ContextCapture] Windows timeout detection and recovery (TDR) error

We  get TDR error when Contextcapture is intensively  processing TileProduction. Would disabling TDR  help or it is driver issue? Does Contextcapture can handle TDR errors or the Tiles should be reprocessed?

OS:Win10 Pro

RAM:64GB

GPU: GTX 980 Ti (driver 369.09)

  • What is GPU load while processig if using GPU-Z tool?
  • Theses are my results. Semms strange that so few memory of my GPU is used, or ?

  • Hi Florent,

    In order to make sure this card (GTX 980) is well used by ContextCapture could you check the following :

    - Run CCSettings.exe from C:\Program Files\Bentley\ContextCapture\bin folder
    - Click on System information tab
    - Can you send a screenshot of the Display adapters ? if you have 2 adapters there is chance contextcapture is not pointing to the NVidia card but another one (intel chispet for example)
    - Also can you click on "start benchmark" and note the score you obtain ? For information I have the same GTX 980 and same drivers version (and updated with latest windows 10 update too) and my score is 119.8/100

    If your card is OK, can you tell me more about the project you are running ?
    - How many photos and their resolution if possible (Gigapixel value should be fine too).
    - Do you have blocks or do you split the model before you submit the reconstruction ?

    Also please note - in case you changed it - that there is great difference of performance between the geometric precision options:
    - <Ultra> option is taking much longer than <Highest> and <Highest> much longer than <High> etc...


    Best regards,
    Pierre
  • Hello Pierre,

    Here is the corresponding screenshot :

    As you can see, the score is close to yours (117.1).

    Concerning the project, I tested on many different blocks that I already processed let say 2 months ago. The blocks varies including photos (24 Mpixels in RAW from Canon 5D Mark III) from 20 to 300 photos per block. Right now for a concrete example, I am running a project (AT done) with 74 photos used for reconstruction, and it is still calculating the 3D reconstruction after more than 12 hours (started yersteday at 8 pm). As a benchmark, I ran the same project on my colleague computer which has a 1080 GTX and 64 Gb of RAM, and it took less than 3h to complete.

    I do not split the model before reconstruction nor use for theses blocks the Ultra option.

    Any possible leads toward a solution :) ?

    Thanks !

    Kind regards,

    Florent

  • Ok let's check another thing :)

    We suspect the Timeout Detection and Recovery key is not set properly and could impact the performance of the GPU card.

    - Could you open regedit then go to the following path:  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers

    - Can you tell me if you have a TdrLevel or any other Tdr registry keys that are listed here ?

       For example I only have the <TdrLevel> key that is set to (0) which is the value you should have by default.

    Best regards,

    Pierre
