I have this small problem with a graphical glitch that i got. Its kinda immersion breaking for me, so i haven't really left the house at all. I remember i had this exact same problem all the way back in Fallout NV: (its only been a problem since i got these new graphics cards.) Anyways here is a few pictures:

As you can see, it is only the characters. Everything else is fine, its just that the characters are so grainy pixellated.

Here are the specs:

Windows 7 64 bit

Intel core i5-2500k quad core ~3.3GHz

16 GB RAM

AMD Radeon HD 6900 series (2 of them for crossfire if i can, currently disabled tough)

Here are the things i have done about it:

Updated drivers

Checked all ingame graphical settings to see if anything influenced it

Checked most of the settings in CCC (AMD catalyst control center)

As i said, this is an old problem that has only affected the Fallout series, but i can't seem to find any fixes for it anywhere. Any help would be appreciated

Got the same issue on the same graphics card. The 'grains' only appear on characters, nothing on buildings/environment/etc. Tried to fiddle around with graphic settings but wasn't able to find anything that affects these grains.

edit: wanted to mention i didn't have this behavior in previous fallout games

Ok, tried the fix in http://www.gamesas.com/topic/1544434-strange-pixelization-outlining-characters/and it works for my case anyways.

Short version, set the graphics to Low in the preset graphics in the launcher. Then turn everything up to where you want it except for godrays, because godrays are problematic.
