I had TS2012 running with great performance, even while running JR content on large routes, such as Marias Pass X. However, after a TS12 corruption, I installed TS2010. I can't remember right off what my graphics settings for TS12 were, but my TS10 is running painfully slow. I place 1 JR locomotive on a map like Marias Pass X, and everything starts running much slower than TS12 did. What are ideal settings to make TS10 performance better?
