I was surprised as just how much of the PC's resources TS2014 requires, it runs fine on my desktop but is a slideshow on my laptop. (i7@2.0GHz Intel HD Graphics, 8GB Ram, 160GB SSD)
There are a few annoyances in it, like the wheelslip that the A4 has, esp. on the West Coast Mainline
Just starting the scenario at Carlisle in summer and good weather with a consist of A4 and 7 coaches, when you are placed into the 3D world the locomotive starts to wheelslip even tho the regulator and reverser are at 0% and train brake is on at 100%
It makes for a nice change from flight sims and is almost quite relaxing
