Is there any way to disable it? Ever since it switched to the snowy background my wa is laggin like hell. I mean just in the menu's, not the game itself.

open the games folder and load the SlowFrontend_Antiflicker.reg file (double click it and choose yes).

I don't have this file, btw.. I just buy Worms Armaggedon download update and the newest patch, and when I run game snow is slow .. I don't have file what you told ... please helppp :((

Look here...

c:\program files\team17\Worms Armageddon\Tweaks

or something like that.

Downloading the patch isn't enough. You still have to install it ;)
