TF Audio
Sets the strength of the Audio effects output for
games that support TRUEFORCE The Audio effects
will replicate different aspects of your racing title such
as engine note, tire grip or road surface
NOTE:
It is usually recommended that the Trueforce Audio
setting is set at a low enough level to receive the
additional information that it provides without
overwhelming the overall experience Think of the
level of vibration that you get through the wheel of
an actual car and aim for that Some titles provide
additional levels of control within their control options
menus by allowing you to adjust individual elements
of the audio; separating out the engine, tire and road
audio, for example
Force Feedback Filter
Each driving simulation will run the physics and
force feedback at different speeds - some only at
60Hz, with others 300Hz or more With a highly
responsive direct drive wheel, it's desirable to filter
out frequencies above which the simulation can't run
at If you leave this at its default AUTO setting, then
this will cover the vast majority of simulations and
provide a smoother experience If you wish, you can
manually adjust this with settings from 1 (least filter)
to 15 (maximum filter), allowing you to feel some
more of the smaller effects that some titles produce,
at the expense of introducing a bit more noise into
the force feedback
