This problem has resurfaced on a Win7-64bit pc with an Nvidia Quadro 4000 video card, using Nvidia driver v320.00, running MicroStation ss3 v8.11.9.357. Specifically, the display may freeze, then black-out, then recover with an error message, as previously reported. For us, this error was repeatable, and occured when zooming in and out while in the middle of the place dimension command.
The workaround reported in http://communities.bentley.com/products/microstation/w/microstation__wiki/4172.aspx does seem to cure the blackout problem.
This problem was previously reported, and was supposedly fixed with Nvidia driver version 307.32 and/or 307.45, depending on the version of video card, according to bentley.
I will download and install that version of driver to see if it cures the problem as previously reported.
Reproducing these TDRs on a regular basis such that they can be debugged has been the single greatest challenge. If you could send your QV_GLSTATS to me that would help. I would especially like to see it with the 320.00 driver still in place and without the workaround, but I can just make note of the differences if you prefer to send it as is. It may help to send a specific DGN that you have had it happen in (if possible). Everything can make a difference in reproducing the problem.
1. In your environment, set QV_GLSTATS=1
2. Run MicroStation.
3. This will generate output in a MicroStation Text Window at the start of the run, which will contain OS information, graphics card / driver information, and information specific to QVision.
4. Cut and paste that information in an e-mail to me, russell.smith@bentley.com, or post the results back to this forum.
About switching to the older driver... It's possible that the older driver could be different enough that the TDRs stop happening, but I would expect that any fixes made earlier would be carried forward, so generally, the latest driver is your best bet. If the TDRs happen frequently in what you do, then using the workaround until the next driver comes out is definitely the way to go.
Thanks,
Russell
