When I play scenarios, ususally by Elphaba's workshop, on the Northeast Corridor route, the sim usually crashes/freezes some time into the scenario.
My PC is fairly powerful, and routes such as London-Brighton, WCML North, WCML over Shap, GEML, ECML, Marias Pass and Surfliner all run without fail or even much stuttering. Is the NEC especially demanding, or is it just unstable?
The NEC in question is the New York-Philadelphia one, I don't have New Haven yet.
