I have the video settings set to maximum aka ultra or high quality and have left the tress and grass settings at default.
When ingame all the grass and tress are showing blue dots/particles.
I tried changing the trees and grass settings but the problem remained, I then tried the HDR settings and lowered it and it fixed the problem to a certain degree.
I am not sure if its a hdr problem or something to do with the trees and grass.
All video settings to max.
If the blue spots can be seen at your end, then try lowering hdr to see if it helps remove the majority of the blue spots
I run using win 7 ultimate 64, i7 930 cpu, 12 gig ram, xfi platinum, evga 680gtx classified 4gig.
This person has also reported the issue and its exactly the same problem that I am suffering from and he has uploaded a picture showing what its like.
