Problem with Microstation v8i ss3; screen goes black - NVIDIA doesn't respond

I can confirm these Problems with Nvidia Quadro Driver 320.0, even without using Microstation, Win 7 64 with other products only.

Our firm has been patiently waiting for some time now after being told from Bentley that their developers were "working with nVidia" to resolve the DirectX11 problem.  I understand that a temporary workaround solution is to revert our workstations back to DirectX9 but we view that as only a temporary workaround and any suggestion that we should view this as a long-term solution is a somewhat inferior response to the issue; we do not view this as a viable long-term solution and my understanding from prior conversations w/Bentley personnel has been that Bentley does not either.

We're running Quadro4000 cards on Dell Precision workstations w/ Win7-64bit.  We did notice a reduction in the occurances of the familiar usually momentary black screen w/ auto-recovery but occasionally fatal lock-up video driver error when the v311.50 nVidia driver came out but the errors were still occuring.  And we confirmed that at the next driver (v320.? as I recall) the problem still existed.  We just downloaded the latest performance driver for this card (v331.65) and still I see no listing for any Bentley app in the global presets pulldown options distributed with the driver.  And still If one navigates to the certified drivers portal on the nVidia site and drills down to the Bentley certified drivers page we see that the latest BentleyMicrostationV8i certified driver for Win7-64bit = quadro-win7-winvista-64bit-258.96-whql with a release date of 2010-07-19.  This finding is not yet supporting statements from Bentley that they are "working with nVidia to resolve this problem".  Mr.Smith: Can you or someone else w/ Bentley please let us know if indeed this problem is being worked on at all and if so what your target date is for a resolution?  Thank you.

We're running AECOsimBDv8i-SS3 (v08.11.09.376). I am not aware of us having encountered these video error problems with any of the other applications which we run and several of those programs are similarly 3D graphical in nature.

We use the Dell systems also and are very disatisfied.  They are like a model T and last, but they are the low end of tech.  The video is a good example - it is very low end for the price.  (at least what the govt pays for their machines)  

There are very cheap cards and better cards that can be added to replace those.  This is not a suggestion to buy as I know this is a pain,  but another workaround.
