The game seems to be stuck in a high Depth of Field effect. It's very distracting. The effect looks something like I'm in a dialogue with someone, or aiming down sights, or taking a bullet to the face. Saving/reloading or restarting the game does not fix it. I've also tried aiming down sights, entering dialogue so see if that resets the effect. It didn't help. Everything also seems to glow green now for some reason.

Does anyone know what causes this? Or how to fix it? It's VERY annoying...

EDIT (SOLUTION): I found a solution after a bit more googling. This can happen when using a gun with night-vision scope. To fix it you need to open the console and type the command "rimod 00094636" without the quotes. The effect should be gone now. If you don't know how to open the console it's the tilde-key on US keyboards (the one to the left of your 1 key). If, like me, you're using a different keyboard try the keys that are specific to your keyboard language (Mine was the ?-key since I'm using a Norwegian keyboard).

Yeah I was just about to post a link here to another thread which contained your fix. You may want to edit your title as well to show SOLVED or something so people will click on it for the solution.
