Love it or hate it, motion blur is in TDU 2 and sadly Eden didn't manage to give the choice in the options menu to turn it on or off. For some this doesn't matter, but for others it can cause them to feel a bit unwell and most agree that it just doesnt look good and/or affects performance negatively.

Firstly, let me start by saying the only way to force it off is by using a method to externally alter a line of code in the game file.
The good news is that this change is so minor and normal that it does not have any harmful effect on the validity of the game files.

It is literally changing a number from 1 to 0

The reason for this guide is due to the fact that you do need to unpack some game files to be able to alter the 1 to a 0 and then repack the game file.

Finally, a big warning...

DO NOT OVERWRITE ANY GAME FILES WITHOUT FIRST BACKING THEM UP BY MAKING A COPY OF THE ORIGINAL FILE BEFORE YOU MAKE ANY CHANGES

If you fail to make a backup copy of the file we are altering, you won't be able to revert to it if you ever want to in future!

As I said, we need to unpack the game files and make an edit.
To do this I use this website article.
http://forum.turboduck.net/threads/31822-any-way-to-disable-motion-blur

Yes you could just go there and follow it like I did, but what if that article vanishes off the net?
So here's a guide on Steam to follow if that ever happens.


1) Back up your original gamepc.cpr file
To do this just go to where you installed TDU 2.
For most people it will be in
C:\Program Files (x86)\Steam\steamapps\common\Test Drive Unlimited 2
but if you install your steam games to a drive other than your primary then you will have something like
E:\steamapps\common\Test Drive Unlimited 2
or D,F,G etc

Once you are there find the file
GamePC.cpr
and right click it and go Copy then go to your desktop and click paste.

Now go find it on your desktop and right click it and go copy then paste it on your desktop
This will make a file called
GamePC - Copy.cpr
This will be your back up.
Now make a new folder called tdu2 and copy the 2 files into it.
Now cut this tdu2 folder and paste into C:\

2) No really, go and do step 1 and make a back up of the file!

3) Download TDU Dec from here
http://aluigi.altervista.org/papers/tdudec.zip
http://aluigi.altervista.org/papers.htm#tdudec

I will upload tdudec to somewhere so it will always be online in case the above link ever vanishes. Until I do though, get it from aluigi and if you can't, leave a comment here saying it's down and I can send you mine (short term as I will put the files online myself very soon eg within 7 days).

4) Right click tdudec.zip and extract it.
Now go to where it extracted and copy tdudec.c and tdudec.exe and then paste them both into the C:\tdu2 folder

5) Now click start and type cmd
A command prompt result will appear, right click it and Run as Administrator and choose Yes on UAC.
A small black box will come up.
Type
cd\
and press enter
now type
cd tdu2 and press enter
now type
dir
and press enter

you should see the following 4 files

GamePC - Copy.cpr
GamePC.cpr
tdudec.c
tdudec.exe

now type
tdudec
and press enter

The following comes up

Usage: tdudec <d/e> <input> <output> [type]

by default type is set to 0 for decrypting the savegame/playersave files,
use 1 as type for decrypting other files (like .btrq, .db and so on)

So we need to type

tdudec d GamePC.cpr GamePC.cpr 1

now press enter

press
y
and then press enter

Leave the black box open as we will need it later.
This has now decrypted the GamePC.cpr file meaning we can now open it in notepad and change the motion blur setting to disable it.

6) Edit the GamePC.cpr file to disable motion blur
Now go to your c:\ tdu2 folder and open GamePC.cpr
It will ask you what you want to open it up with and you should choose notepad but untick the box offering to open it in notepad everytime.

Now we can see all the settings in the GamePC.cpr file
Scroll about a third of the way down and find PostFX or you can just press Ctrl+F to bring up find and type
PostFX
and press enter

This will go to the section we need which has the following

PostFXEnabled = 1
ENABLEMOTIONVECTOR = 1
MV_FPS_RESCALE = 1.0
MV_FPS_RESCALE_MIN_STRENGTH = 0.0
MV_FPS_RESCALE_MAX_STRENGTH = 5.0
MV_RADIAL_BLUR = 1

All we need to do is change the
1
to a
0

on the option my radial blur. That is a number 0 eg zero by the way ;o)

Once you've done that click save and close notepad

7) Encrypt the GamePC.cpr file

Go back to your black command prompt window and type

tdudec e GamePC.cpr GamePC.cpr 1

and press enter

now press
y
and then press enter


This has now encrypted the GamePC.cpr file meaning it is now ready to be copied back to the game install directory.

8) Copy GamePC.cpr and paste it into your TDU 2 install directory

eg
For most people it will be in
C:\Program Files (x86)\Steam\steamapps\common\Test Drive Unlimited 2
but if you install your steam games to a drive other than your primary then you will have something like
E:\steamapps\common\Test Drive Unlimited 2
or D,F,G etc

9) Now play the game as normal and enjoy no motion blur!
