Well it seems like the 'serious' racer are all getting the same impression about the FFB, that its not even up to Assetto Corsa standards. How about the tire feel and general car physics, how do they feel with what you have tried so far?
I really hope S-397 can start to improve their marketing and polish on the rF2 brand, as I fear they may not survive unless they get with the program and give it more mass market sim racing appeal. The new UI will help but that alone will not be enough. They missed out on a huge opportunity when they got all that great publicity for the WFG, they really should have be able to present more of the future and some firmer launch dates for the updates.
