ArmA2 / OA (low) performance issues

[ArmA2 / OA (low) performance issues]

Hey!

I recently reinstalled Arma 2 Operation Arrow Head and Arma 2 Free.

Upon installing the DayZ mod again and joining a game, I find that

absolutely no server I join, provides a good frame rate. In fact it drops

to 5fps when I look straight across the landscape in Cherno. When I

look up into the sky it will give me about 15fps.

This is a ridiculous drop in fps from what I used to have. I have no idea

why it is so low.

Some which is odd that I did notice though, is that the writing on the

screen is distorted and blurred as though it is in a very low resolution.

Everything is almost impossible to read.

I cannot see any reason that I would suddenly get ridiculously low fps

when I previously ran the game at around a very playable 35-40 fps.

My specs are:

Intel i3 4 Core M 370 2.40GHz.

8gb DDR3 Ram.

64-bit OS.

NVIDIA GeForce GT 420m
