+Playable. I've made some improvements to the dynamic updating of effects, and
+while still far for perfect, the experience is slowly getting better and better.
+Some drawbacks include missing dynamic updating of ramp effects and in some
+games inconsistent pedal mapping. Meaning that all pedals should be detected in games, but may be mapped incorrectly.
 
 Anycase, **this version is usable in most force feedback games, supports
 rangesetting as well as gain and autocentering along with most force feedback effects.**

-    + Currently there is no support for this driver in oversteer(https://github.com/berarma/oversteer), but ffbwrap(https://github.com/berarma/ffbtools) should work.
-    + If the wheel has a deadzone in games, you can set up a udev rule:
-        `/etc/udev/rules.d/99-joydev.rules`:
-        `SUBSYSTEM=="input", ATTRS{idVendor}=="044f", ATTRS{idProduct}=="b66e"

-        RUN+="/usr/bin/evdev-joystick --evdev %E{DEVNAME} --deadzone 0"`
