I'm having graphics card problems running Simulation in 2011 SP3. The bolt check plots are not working (this may be a software issue) and some of the faces are not showing. On occasions the model completely disappears.

I'm using the driver for 2010 because I usually use 2010 SP5. Is there a way to download both drivers and quickly switch between the two? I seem to recall this is possible. If so, how have people found this? Given the flaky nature of the graphics card software I'm reluctant to try.
