Racked! is my attempt to redo the forcefeedback in Dirt Rally so only realistic* forces are felt on the wheel, with all the "for effect" stuff removed. I took the approach of trying to use the different FFB effects available to simulate a steering rack only. The result is pretty awesome!
Extract the "forcefeedback" folder inside the zip into your games installation folder
Extrace the "forcefeedback" folder from the "originals" folder inside the zip to your game's installation folder.
FFB in Dirt Rally can be split into two categories, Force and Effect.
Those in force are driven by physics and constantly updated in near-realtime. Effects are triggered by thresholds and play "samples" for very-short amounts of time.
The first 3 settings in the game are Force type :
Self Aligning Torque
SAT has only one setting and thats strength. Its driven directly by the physics engine and so how it functions doesn't really change between mods. Instead the below are set to effect SAT!
Simulates the stiffness of the steering rack (set to very light), and the varying resistances introduced by the power-steering system under extremes. Mostly effects SAT by varying the force through friction on the wheel. Also adds/removes friction according to surface type.
Simulates the wheels being forced to a new direction by the surface (such as bad landings, ditches etc) and also surface based sliding friction.
These settings should be lowered or increased as a set. If the wheel is generally too-stiff for your liking, lower these by 3-5% equally.
These are Effects. They are triggered by thresholds, and play samples (a wave amplitude to represent a vibration of a certain speed and sharpness)
Simulates additional resistance to turning through extreme compression and VERY subtle underlying vibrations on rougher surfaces.
Simulates road surface based vibration that is felt while "controlling" the wheel. Extremely subtle
Also adds a very small amount of vibration at extreme slide angles.
Unchanged from the original, just reduced in strength. 10-15% gives noticable vibrations but no clunking.
Any of these can be turned off completely or lowered dramatically.
It is important to note that Suspenion was reconfigured "in-file" and as a result needs to be set high to feel anything from it! I did this as suspension is the big clunker in Dirt Rally, and causes most of the wheel noise!
Start with these settings in-game (Workshop file coming when it lets me upload!) :
For Logitech Users :
The result is a completely different feel to the game. What you mainly feel on the wheel is direct forces resulting from your driving, and "underneath" that you feel varying types and strengths of friction and vibration that are caused by the effects.
For those looking for a more "silent" FFB solution on their G27, this is for you. The wheel becomes almost completely silent.
I think people with the high-end wheels who find Impact a bit over-the-top will enjoy this too!
I prefer Impact v7 myself, but I thought I would release this anyway. As a result there may not be any updates
you can't really do ffb screenshots so :
