I'd still like an explanation why erocker closed the GRID 2 Discussion thread (as in GENERAL discussion), and replaced it with this mp one that doesn't seem to be any more popular than that one was? I don't like to have to post in this mp biased thread that's off in clubhouse land vs the general Games board every time I want to say something about the game's sp.
Anyways, I've been experimenting with the game's input folder and have found editing the "dinput_default.xml" can make quite a bit of difference in car handling for those of us using unsupported control devices that were supported in GRID 1. Unfortunately there's no Linearity value, but what's there helps a lot. The selected settings here are specifically for keyboard.
Here's a before and after vid showing the same event raced without and then with the file edit. It's the season 4 ESPN Togue at La Turbie Cote D'Azur in the Audi RS5 on Hard. On keyboard it takes the twitch out of the steering, gives you better traction on starts, and helps avoid spinning out when accelerating out of turns. My time on this run improved by 3.6 seconds with no scrapes.

The video description explains how the edit is done, but here I'll show you the before/after for the section of script edited since YouTube would not allow it in the description. Again, the file to edit is "dinput_default.xml", located in the "input" folder of the GRID 2 directory. It's best to set aside a copy of the default file before editing.

<Action id="Steer Left">

<Axis id="di_slider_0" type="biDirUpper" deadzone=".25" saturation=".50" />
</Action>
<Action id="Steer Right">

<Axis id="di_x_axis" type="biDirUpper" deadzone=".25" saturation=".50" />
<Axis id="di_slider_0" type="biDirLower" deadzone=".25" saturation=".50" />
What the above results in is changing the acceleration and steering saturation from 100% to 50%, and the steering deadzone from 20% to 25%. Alternatively you could lower vs raise the steering deadzone, and drop steering saturation even more, but it might cause too much under steer on tight tracks with lots of sharp turns, forcing you to use the handbrake more, which is less precise.
