This mod is inspired by Ryder25's mod for F1 2012.
Guess he will come out with it sooner or latter. Since I missed the option very much, I have decided to try it myself and here is the mod which enables the options. Just make backup of states.bin in the system folder and replace with the new states.bin.
Please refer to the old thread for details. There are 2 more options than 2012 i.e. enable infinite flashbacks (edit: not working for me) and toggle flashback anim to false/true.
Edit: The following options may have no effect:
Demo weather, Reduced Mechanics, Enable infinite flashbacks ( Don't ask me why and what are they for as CM made them and I only made them visible for use)
Warning: Use this mod at your own risk. There are bugs in flashbacks (not sure is this mod or original bug in the game), so do not use enable infinite flashbacks and toggle flashback anim options.
The option menu is available when you are on the track. Except online race (never try), It should work in all modes including career mode and it did not corrupt my game. Nevertheless make backup where necessary.
