What is this? It makes all the foilage shimmer. Small ropes, poles and edges also shimmer.

update: found no solutions. loaded months old drivers, cleaned the computer, tried both nividia inspector and usual control panel: nvidia gtx 770. the trouble is in all games, but much worse in this one.

I'm looking at this picture and I'm telling you, I don't see anything wrong with it except a little bit of bad grass shadowing. I wanna say you're overreacting :<
