screen flickers

[Topcu]

No problem until the map opens. When the map is opened, the screen flickers. White lights flickering. This problem makes the game unplayable. How can I fix. Please help me. Also comes a post like this: "Warning: Your windows Virtual Memory swap file is less than the minimum recommended size of 140 mb. You may have to reduce video detail settings in the game in order to play DFLW. Please refer to the deadme.txt for more information"
