We're liking the free Tuna character rig, downloadable for free from Highend3d.com. He's relatively light, at just 9MB, and he should give you real-time playback in your viewport. So far we haven't uncovered any major flaws or weaknesses.
Eye Direction control settings
To get the eye direction controller to work at its best, you need to change the settings. Go to
tuna:AimEye_M, and set follow to 1. This way the eyes will follow the eye direction controller, even when you move the head around.
Modelled by Ugur Ulvi Yetiskin, and rigged with AdvancedSkeleton, this well-crafted character rig looks to be a good option for students studying character animation.
