You can count me in as one that is desperately in need of in-game deadzone adjustment. My controller, like a lot of PS2-USB adapters, does not use any sort of custom driver, and as a result uses generic controller drivers provided within Windows; this generic driver does NOT have any sort of deadzone adjustment available.

Live for Speed is amazing, but it is incredibly twitchy driving a front-wheel drive car, and it is absolutely impossible to maintain a smooth heading in a rear-wheel drive car because every tiny movement of the analog stick in its' center positions is registered in-game. Not even DXTweak2 has worked, LFS seems to ignore the deadzone adjustments I make via that application
