Well, with the last updates, there are some new graphical options, and I don't know at all what they are doing...
Can someone help me ?
Here are the options :
- Vignette
- Film Grain
- Chromatic Aberration

Thanks in advance :)

"Vignette" usually means adding darkening to the corners of the screen like applying something like this mask: http://i.cubeupload.com/H8EHd4.png

I should have thought of looking in wikipedia XD
Well, I guess this is as simple as it sounds for Film grain, but I didn't noticed when there was, maybe I simply didn't paid attention :P

For Chromatic aberration, I would conclude by "the effect of a kind of distorted light/vision". So certainly a lot resource consuming (and so not for me). Oooh ok, I see.

Thanks you two for your help :)

Any ingame examples with/without those options, please ?

it helps with streaming media so not something most people need to worry about
