Black Screen, No geometry

  Discovery 2020R2.5 opens, but there is no geometry visible and no triad. I have attempted to both create new models and open old ones. I am using windows 10 with a Quadro P3200 graphics card with the latest drivers (452.57). Discovery was working fine when I last used it a few months ago and now it is unusable.

  Hello Sam ,
  
  A similar issue has been encountered before with Discovery on which the developers are working now to improve.
  
  The main cause of this is identified to be the latest NVIDIA driver version (457.77, or the entire 45x.xx driver series in some cases), which is working on some machines, but for some machines, it does not work. A workaround for this will be to revert back to the older driver version (426.78).
  
  A bug (Bug ID:323999) has already been filed for the same. Please refer to these two threads (1, 2) which discuss this problem in detail.
  
  If the problem is not solved with the given suggestion, please let me know so that I can investigate further.
  
  Regards.

  Charudatta Bandgar , Reverting to 426.78 did the trick. Thank you for sharing the other threads as well. In my searching I did not find them.
  
  I have marked this as resolved, thanks for the prompt help!
