Okay, so maybe I’m a bit weird for even trying this, but for me, driving games aren’t all about fast supercar races all the time - for me, one of the big draws of the Forza games has always been the huge and varied car selection and the opportunity to set up strange, exotic races. So I just had to try and see how the BMW Isetta performs on ice in a full blizzard and set up a single-lap, Isetta only exhibition race on one of the tarmac/ice circuits in the village - and I got so thoroughly trounced by the AI drivers that I think something is seriously off here.
I tried both my PI-abusing D100 build from the base game (basically, install everything that doesn’t move your PI rating above 100…if you stay at 100, the AI opponents don’t seem to tune their cars at all, and with a car as lightweight and underpowered as the Isetta, every single tuning part you can install makes a huge difference) and a completely stock Isetta, both with and without snow tires, and the results were always the same - my car maxes out at 30mph and absolutely refuses to go any faster while the AI opponents zip by at their normal blazingly fast Isetta speeds, with me finishing the lap in about 3 minutes and all the AI opponents finishing in just about 2 minutes. This seems seriously off, especially considering that at that speed I was just driving full throttle all the time following the ideal line without ever needing to brake or let go of the throttle, so I think we can exclude driver error. What’s going on here? Did I discover a game-breaking bug?
For the record, this was on my normal difficulty settings of highly skilled opponents, all assists off except normal steering - I didn’t have the patience to try with different difficulty settings, but I don’t think it would make that much of a difference.
