Borderlands (UE3) ini tuning

mess with the ini files and Nvidia Inspector

Best performance for the majority of U3 and U2.5 engine games - 0x000100C5 (issues in some u3 engine games).
Even when nvidia uses a different one in their official profile, you can often gain significant performance
just by changing to this flag.


BaseEngine, PCEngine, DefaultEngine, Engine and UserEngine.ini etc
[Engine.Engine] and [Engine.GameEngine] (all instances you can find bSmoothFrameRate)
bSmoothFrameRate=TRUE
MinSmoothedFrameRate=45
MaxSmoothedFrameRate=120
TerrainTessellationCheckCount=12 (doubled 6)(This is the number of frames that are used between terrain. tessellation re-calculations. More for performance.)
TerrainTessellationCheckDistance=8192.0 (doubled 4096.0)(The radius from the view origin that terrain tessellation checks should be performed. If 0.0 = infinity.)
FluidSimulationTimeLimit=60.0 (Time limit (in milliseconds) for a fluid simulation update, to avoid spiraling into a bad feedback-loop with slower and slower framerate. This value is doubled in debug builds. So you should increase that value for higher performance.Default 30.0)
PhysXGpuHeapSize=96 (Defines main memory allocated to PhysX, the more, the faster textures and data are stored and used by PhysX enfine. If you are using PhysX might consider increasing this.)
MaxParticleResize=7000 (double the ingame value) (The maximum allowed size to a ParticleEmitterInstance Resize call. If value is larger, the function will return without resizing. 0 = infinite. Adjust the value between 532 and up. 532-10,000 is a good range for limiting the particles.)
(BAK had it at 0 lol)
[TextureStreaming]
PoolSize=768 (no more higher or problems)
MemoryMargin=192 (Poolsize/4)

DefaultSystemSettings, BaseSystemSettings, SystemSettings, UserSystemSettings.ini etc
[SystemSettings]
MaxFPS=120.000000
MotionBlur=False
DepthOfField=False (some games requires this to be true to work without glitches)
ChromaticAberration=False
FilmGrain=False
UseVsync=False
MinShadowResolution=512
MaxShadowResolution=1024
bEnableBranchingPCFShadows=True
bAllowHardwareShadowFiltering=True

AllowRadialBlur=False
MotionBlurSkinning=0
MobilePostProcessBlurAmount=0.0
MaxAnisotropy=0 (force it through nvidia control panel instead)
ShadowDepthBias=0.009

DefaultInput, BaseInput, Input, UserInput.ini etc
[Engine.PlayerInput]
bEnableMouseSmoothing=False

[UTGame.UTConsolePlayerInput]
bViewAccelerationEnabled=FALSE


DISABLE STREAMING (HEAVY solution so backup *game*Engine.ini, depends on the game if it helps ofcourse)
USE MODERATE PREALLOCATION IN NVIDIA SETTINGS
[Engine.Engine]
bUseBackgroundLevelStreaming=False
bUseTextureStreaming=True
OnlyStreamInTextures=True
MipFadeInSpeed0=0

bAllowSwitchingStreamingSystem=False
UseDynamicStreaming=False
