Hello, thanks for your message, I am putting together a user guide so when this is done I will make this available. Race speed does reset to normal when leaving/returning to race view, it has to do this and can't really be changed unfortunately.
I can take a look at an additional game speed option. Scouting is something that is set to scout one rider at a time, I may be able to increase this to 2/3, will see what I can do. As for game performance at the French GP - there is no reason for this as nothing special happens for this event, but will look into it.
Glad you like the changes to the demo though, I do listen to player feedback and make changes where I can - hopefully the full game isn't too far away from being completed.
