Depends. Supports are worse than 3ds for me, but 100 is what I usually get on light rides. But again, my PC is nearly 5 years old, so I don't think anyone will have any trouble as long as they're not running it on a netbook or something. This ride was between 60-100 for me most of the time, dropping into the 50s at the lowest.
I'd say this ran about the same on my computer as Aytrane's Orient Express recreation. Try downloading that and see how it runs for you.
