That´s the depth of field.

Been looking this way since Armed Assault times. I´ve thought about making a ticket on this, but I thought that they wouldn´t change it anyways and didn't bother. Instead I just turn depth of field off completely.

I doubt there's a way to fix this, really. No matter how high your settings, everything will look square. Even the particle effects are square when looked at from above.

Nice to know thanks. At least turning depth of field off will release me from this pain^^

Issue closed as obsolete. If you encounter this problem again, please create another ticket. Thank you.
