Playing it on Hard with all assists turned off and full simulation rules damage fuel and tyre wear.
So far finished 13th, 4th, 20th and 16th. AI fluctuates too much, some tracks they are fast some they are slow and the pit hold up is really irritating and costs a lot of positions if it is timed wrong but overall its great fun!
Only other problem I have is that whilst its easy to spin which is realistic, I enabled 3 flashbacks but sometimes they seem to reset you just before the corner and if you try and turn straight away my car goes forward for a second or two which means it was pointless using it anyway...
Would give it 8.5/10, well worth a buy and can't wait to sign for a better team than Lotus. Top speed is awful compared to AI even with low downforce.
