I know this issue was reported on PC earlier with a few other routes but I have not long finished playing a scenario (Catch Up) on London Commuter and there was a lot of stuttering with the visual and the sound effects as well. It was very prominent around major stations; Gatwick Airport, East Croydon, Clapham Junction and London Victoria but also whenever you passed other trains, the frames, sound and visual quality seemed to really lag Also, there was a severe drop in the lighting as you entered London Victoria, almost like you had entered a long tunnel I'm on the Playstation 5 using the PS4 version of the game, played on the Great Western Express and Cathcart Circle with no issues and about to try the Nahverkher Dresden route and see what that's like
