PAINKILLER

Overdose requires both good CPU and Graphics processing power for an optimum playing experience. If you find your framerate to be too low, please adjust your video settings under the Options Menu. Dropping texture quality levels for the game architecture, sky, characters, and weapons to lower levels, as well as the overall graphics resolution will help achieve improved game performance. For multiplayer gaming please make sure to set your Connection Speed accurately under Player Settings in the Multiplayer Menu.
Also for multiplayer play on the Internet behind a firewall and/or proxy server please make sure to have the required port open to connect. Painkiller: Overdose by default uses port 4974. Painkiller: Overdose will not connect without an open port. Note GameSpy Arcade utilizes additional ports.
Information on some of the following topics has not been included or has changed since the printing of the manual: Checkpoints: Save checkpoints on both Daydream and Insomnia modes replenish your health fully. Headbob: The option to control the amount of walking and head motion you see while playing has been included in the HUD settings under the Options Menu. Lowering this setting will lessen the character's motion. Clip Plane: An option to control the viewing distance in the game world has been included under the Advanced Video tab in the Options Menu.
By lowering this setting you may have improved performance but you will not be able to see as far into the game world. Audio Settings: On certain configurations it has been noted that selecting the "Miles Fast 2D Positional Audio" driver as the Sound setting under the Options Menu will prove to be more stable than other hardware drivers. Low-end cards: While Painkiller: Overdose supports most older video cards (see System Requirements above), some of Painkiller: Overdose's special effects and advanced graphics features are not supported by these boards. While this will not affect game play in any way, some visual effects may be reduced or disabled entirely on lower end video cards.
