Also posted on Facebook. I am well aware I am posting about known issues but from the Arosa streams feedback has been encouraged by all involved. Well now I have actually played Arosa for the first time tonight to see what it is like. Beautiful job Rivet. Really fantastic job capturing the essence of the route, it's really lovely. I really don't think it deserves some of the so harsh negative feedback.The locos and coaches are modelled beautifully. Sure distant scenery and trees could be better but on the whole I am very impressed with how it looks and feels. However as everyone is already aware there is an issue with the driving dynamics. If you try and drive as is prototypically correct(as Jasper said in the stream). That is: 40% Train brake and adjust the traction motor brake when required. There is a sort of reverberation through the couplings as they bounce against one another. As if there is to much springing effect in the couplings but no damping effect. A bit like the suspension on a car if it has a knackered shock absorber. The spring effect just keeps going with nothing to dampen it. You can see the effect in game watching the speedometer start oscillating up and down up until the point it get so bad there is a derailment. You can still notice the effect very slightly even if just using train brakes but never to the extent of derailing the train. I'm guessing it can be fixed with editing the coupling springing/damping effect if I'm interpreting the problem correctly. I got the impression from last night's stream that Matt and the Rivet team know exactly what the issue is and how to fix it.. Only other criticism is I haven't noticed any jointed track sounds, going over points etc. I know the carriages have quite a distinct running noise but no track joints. I could be wrong... But on the whole I think I'm really going to enjoy playing this one. I am looking forward to the patch to fix the derailing problem .
