Codemasters have released the fourth PC version patch in their on-going effort of ironing the kinks out of their recently-released F1 2013 title.
The patch addresses various issues as listed below, the patch is available via Steam. A console patch including the applicable fixes is currently being tested and will be available later.
Mid Session Save
Fixed a bug which prevented car setups from being loaded correctly when a mid session save is created while on track in any session.
Added a DRS Bleep sound to inform the player via audio that the DRS is available. This sound is quite subtle so that players who do not rely on this are not distracted, you may need to lower the engine volume and raise the effects volume to make this clearer during gameplay.
