Just asking about the 11-way driver comparison. Specifically, The image in the first column. Is there graphical corruption on some of the 3D rendering from the images you took? Seems like there's a weird extra thin strip of 'skin' that is rendered after what looks like an human elbow.
It seems like that weird graphical glitch appears on one driver and disappears on the next one.
The image in the first column was from Doom 3 when the player had his fists drawn and was standing in front of the wall. To be life-like with breathing, the hands do move a bit, so due to a very minor timing issue, you may be seeing more of his fingers.
