Hey guys,had the same problem on an MSI-GE62, win10 version 10.0.10586, nvidia optimus driving a GTX960M plus integrated graphics.
running 4.33U1, entering 3d in 64 bits mode always crashed the sim, 32 bits mode worked without any problems.
as reported here by others, the workaround to enable 64 bits mode was to enable Cockpit Display in External Windows under External Display in Configuration>Hardware: the 3d world will then start in a window and run just fine.
guess we have to wait for a full troubleshoot but that’s fine enough for the moment. keep up the good work boys
