It's not possible that GSX alone could crash the sim.
GSX runs entirely externally of the sim, under the Couatl.exe interpreter so, by definition, and external .exe doesn't have the means to crash the simulator, since it doesn't have any access to its process.
What *might* happen, instead, is that a wrong graphic setting or tweak, either in the driver on in the simulator, might cause a crash of the sim when a GSX object is created. The object of course it 100% fine but, it's possible some bad driver/sim tweak might result in the sim crashing when creating what is an otherwise totally 100% standard object.
You don't say which simulator you use, which can be very important in this case.
