Blurry Vision?

[Skell (DayZ) 1]

Well as it says but the thing is people say its because I havn't drank or eaten anything or a Zombie hit me, etc.

Nope Wrong, I get it at the start and im even surprised im still alive for like 3 hours with this vision of mine and im sure others have this problem but im not totally sure if its my video card so I will post it in a sec just wanna say how the problem is.

Basically if I do Normal Vision the land is alittle blurry to me if I do High Vision what happens is I can see better abit byt I run around laggy like I freeze then go to where I was running towards to all jumpy like, if I change the 3d Resolution with my monitor I see alot better but it forces the Vision to High so that makes me all jumpy again but when I change the Vision to Normal it forces the 3D Resolution to what it was before which I think is 980 or something and my moniter is 1080 somewhere around that, so can anyone help?

My Video Card

NVIDIA GeFource 9500 GT
