Yeah, I know the title sounds like a dodgy channel 4 documentary, but can the team take a look at East Croydon station when the station lights are on and see what's causing the fps issues here? During the day I get 60fps, but when the station lights are on this tanks to 6 (Yes SIX!) fps. If you rotate the camera away it goes back to 60fps. Absolutely no problem during the day.
