If you ever watched Best Motoring TV program and especially their Drift Bible, you might have noticed the so-called "g-balls" indicating acceleration forces acting on the car.
This plugin is a simple simulation of this balls so you can somewhat compensate with your eyes the missing acceleration forces feedback acting on your ass in real car :)
It uses d3d9 proxy dll from http://www.rfactorlive.co.uk/ and well, even plugin itself based on the skeleton of rfactorlive sample rendering plugin. Thank you, guys!
Plugin is pretty customizable. You can change ball basket location, size and forces scale. Sample ini file with build-in documentation is provided.
To install plugin just extract it to your rFactor folder.
