Head to the following file location: Users/*user*/AppData/Local/TekkenGame/Saved/Config/WindowsNoEditor/ and open up 'Scalability.ini'.

If you want to remove the CA character blur stuff, add the following lines to the file.

[PostProcessQuality@2]
r.SceneColorFringeQuality=0

[PostProcessQuality@3]
r.SceneColorFringeQuality=0

To remove the Film Grain, add this extra line underneath: r.Tonemapper.GrainQuantization=0. So, to disable both your "Scalability.ini" file should read as follows.

[PostProcessQuality@2]
r.SceneColorFringeQuality=0
r.Tonemapper.GrainQuantization=0

[PostProcessQuality@3]
r.SceneColorFringeQuality=0
r.Tonemapper.GrainQuantization=0

The PostProcessQuality@2 and 3 stuff refers to High and Ultra settings respectively. Probably a good idea to set the file to Read Only after you're done saving it, to make sure it doesn't revert.
