IIRC, Live For Speed and RaceRoom have "decent" clutch feeling. Both game is "free", you can try them yourself.
Other game is simply linear feel or just almost impossible to stall.
Also try to get a full set 2nd hand G27, it's usually cheaper.
1) It's been there since the beginning and you only noticed it now
2) Developers optimized their game/software for better performance and this was the result of it.
