To start this tutorial off, you must have the Unreal Development Kit, or Movie Battles III (when it's released), installed. To find the config files - labeled UDK*.ini (* = specific config file name) - you will need to navigate to C:\UDK\UDK-2011-* or C:\UDK\Movie Battles III, and go to UDKGame -> Config.
UDKEngine.ini holds all of your graphic information. Things like texture quality, super sampling, and rendering will be in UDKEngine.ini.
UDKInput.ini holds all of your binds and controls. Things like your key bindings for movement, and your mouse sensitivity, will be in UDKInput.ini.
UDKGame.ini holds all of your personal information. If you don't have Steam, you will need to set your name in UDKGame.ini. Steam will automatically use your Steam display name if you are, however.
Now to start: Open up UDKEngine.ini in notepad (this will be the one we are going to look at, as it contains graphic options that may or may not speed/slow your computer).
Search for [SystemSettings]
- bUseMaxQualityMode=True/False - TRUE = Runs the game on highest possible settings. This is not recommended for older machines.
- MotionBlur=True/False - TRUE = Smoothens mouse panning. NOTE: With DX11 rendering enabled, this will cause a not-so-faint edgy glow around your character, which looks like shit.
- DepthOfField=True/False - Disabled can improve framerate.
- AmbientOcclusion=True/False - Disabled can improve framerate.
- Bloom=True/False - Adds a sort of glow to all objects in the game. User discretion.
- AllowD3D11=True/False - Enabling this will enable DirectX 11 rendering. NOTE: This is incredibly hardware intensive, and will require a powerful computer with an AMD Radeon 5xxx series or NVIDIA GTX 4xx series graphic card.
- DetailMode=* - Increases detail of objects in the game. User discretion.
- MaxAnistrophy=* - This will control how detailed textures appear. Max is 16.
- MaxMultiSamples=* - (Anti-aliasing) controls how jagged the edges of objects in the game are. Max is 16.
- bAllowD3D9MSAA=True/False - Enables or disables anti-aliasing (multisamples) for DirectX 9 rendering. NOTE: If you're going to use DX11, disable this or your game will crash to desktop.
- Your games resolution. You will need to use a windows allowed resolution (1024x768, 1280x720, 1280x800, 1280x1024, 1440x900, 1600x900, 1920x1080, 1920x1200).
By default PhysX will be disabled with bDisablePhysXHardwareSupport. If you have an AMD graphics card, keep it to true, as AMD doesn't have native PhysX support.
When you've changed what you like, save the file, and all of the changes will take effect as soon as you start up the game.
