Powerdraft problems with windows 10

I have changed my OS to windows 10 but unfortunately I got back same graphic problems I had when I installed powerdraft, the drawings are all jammed together. Would appreciate any suggestions. Sorry I know WINDOWS 10 is new but I believe Bentley has been preparing its launch for sometime.

  • The problem is that the Windows 10 update forcefully updates your graphics drivers. The newer drivers are the ones causing the problem. Updating drivers won't solve anything. The older drivers, that used to work, simply can't be installed on Win10. The official recommendation is pure waste of time in the case of an upgrade to WIn10.

    The problem has existed for years, so don't hold your breath for NVidia to fix the problem.

    The QV_D3DVERSION=9 is the only way to go if you want to keep using MicroStation V8i with the same graphics card on Windows 10.

    If you ever upgrade to MicroStation CONNECT on that system, you'll need to set QV_DISABLE_D3D11=1 or you'll have the same problem again.

    Thank you for the assistance.  Your comments have been very helpful.

    I placed the following variable in the Personal.ucf (this is for Powerdraft CONNECT) and it solved the problem:

    QV_DISABLE_D3D11 = 1

    So Powerdraft is now happily running on DirectX 9

    The machine has the NVIDIA drivers;    3D Vision Driver 341.95,   Graphics Driver 341.95

    On another similar machine with the NVIDIA Graphics Driver 353.3 all is fine using DirectX 11.  I will try to upgrade the above driver to 353.3 as well, and see what happens.

    Koert, my only question is; for Power Rail Track SS2 and SS4 (i.e. pre-CONNECT) where should I put the QV_D3DVERSION=9 variable?  For the above Powerdraft CONNECT I placed it in the Standards.cfg but it made no difference.  PD still insisted on using DirectX 11.

    Standards.cfg shoud be fine to place QV_D3DVERSION variable definition. The workspace structure and some file names are different in V8i and CONNECT Edition, so

    Alternatively you can also define this variable in Windows, not in workspace configuration, so it will be used by all installed V8i products.

    With regards,

    It's pretty interesting findings. I am curious what the result will be and if the newer driver will solved the problem.

  • That would be interesting, however it's probably just not the same graphics card. Upgrading Drivers shouldn't break anything after you've done the update to Win10, so why not give it a go? Do let us know if NVidia actually released a new Win10 Driver that solves the problem. That would be a nice surprise.
    You'll have to remove the QV_... variables to test with the new Driver. Not that you should expect a noticeable performance increase or anything, purely out of curiosity.
