The system used for Train-Sim was a PIII850, with 384 megs of RAM, and a Voodoo 5500. All that yielded a great frame rate, averaging between 15 and 25. The dense forest reduced frame rates over what was seen in the flatlands.
Performance is outstanding, as a general rule.
Check out my shot on my preferences settings for my system. I found this works best for most situations. Part III is here. Last week I left you with my struggles and sense of adventure. In a week's time I have become quite good at driving the steamers but not to the level where I will get graded well in the activities.
