This is what it says in the readme file.
Installing G-Racer
==================
Run the application, it will register on LCD available applications itself.
Those small buttons under the display simulate the hardware buttons on the real keyboard:
1: timings
2: temperatures
3: timings (second option)
4: temperatures (second option)
Activation
==========
Be sure the following option into your \UserData\[playername]\[playername].plr file is set to "1":
[ Game Options ]
...
Write Shared Memory="1"
...
Troubleshooting
===============
If you do not see any screen a/o the LCD screen is flickering, right mouse click on your G-15 Keyboard Profiler, Select LCD Control Panel... and disable any other running application than "G-15 Profiler" and "G-Racer".
If the timing/temperature screen doesn't show any data: check your .plr file ("Activation" section of this document).
===============
G-Racer is in program files and the plugin shows in the keyboard game panel manager.
I don't need to use it but it does look cool
plus you can have a sneaky peek at other folks readouts during practice ( don't tell anyone
)
