When driving the class 66 in GWE you have to read the differential speed signs but motion blur means these are never in focus at moderate to high speed and are difficult or impossible to read. The bigger speed signs can be read, but most of the signs are the smaller ones. One solution would be having an option to turn motion blur off on PS4. Another solution would be to have the correct speed limits for the type of train being driven in the HUD. I've also found that the speed signs in NTP disappear into the background and to be honest I can never see them, I have to rely on the HUD. I'm assuming this is to do with the motion blur too.
