Fail in graphics, please help :/

Well, im pretty sure that this is the transparency effect of the own game, cuz im also getting this. (so you can see yourself even with grass on the way)
And about the characters: http://ffxiv.gamerescape.com/wiki/Stealth_(Fisher)

About the flickering:
Grass shimmering = Turn "clamp negative lod bias" on. (nvidia inspector/nvidia control panel)
Texture flickering (if you move your camera and they only load after half second) = Turn occlusion culling off in your game.
