As we all know, this game has some noticeable texture pop-in, and that's mainly due to the PC version of the game still using Texture Streaming technique of the engine intended for Console.

Mainly, this tweak deals with [TextureStreaming] section of the RushEngine.ini
Since it is IMPOSSIBLE to turn off texture streaming (if you turn it off, you'll have broken textures ingame).

Now, before I give the tweak, make sure you can run this game VERY COMFORTABLY (FPS wise) before trying this, as this puts a large load on the PC. Last thing, make a back up of your current RushEngine.ini (just in case something goes wrong). Now let's start, open up the RushEngine.ini in My Documents\My Games\The last remnant\RushGame\Config

1. bUseBackgroundLevelStreaming=True -> change it to FALSE, I think this disables streaming while you are moving about the field which basically force the engine to load everything up beforehand. This is set to "True" to increase performance I believe.

2. The huge section of [TextureStreaming]

These are the default configuration:

[TextureStreaming]
PoolSize=82
HysteresisLimit=20
DropMipLevelsLimit=8
StopIncreasingLimit=6
StopStreamingLimit=4
MinFudgeFactor=1
FudgeFactorIncreaseRateOfChange=0.7
FudgeFactorDecreaseRateOfChange=-0.6
MinRequestedMipsToConsider=11
MinTimeToGuaranteeMinMipCount=2
MaxTimeToGuaranteeMinMipCount=12
UseTextureFileCache=FALSE
MaxTextureMipCount=13
MinTextureResidentMipCount=7

To optimize it for the fastest possible of streaming (Thereby reducing pop-in) are as follows:

[TextureStreaming]
PoolSize=320
HysteresisLimit=20
DropMipLevelsLimit=16
StopIncreasingLimit=12
StopStreamingLimit=8
MinFudgeFactor=.5
FudgeFactorIncreaseRateOfChange=0.5
FudgeFactorDecreaseRateOfChange=-0.4
MinRequestedMipsToConsider=11
MinTimeToGuaranteeMinMipCount=0
MaxTimeToGuaranteeMinMipCount=0
UseTextureFileCache=TRUE
MaxTextureMipCount=13
MinTextureResidentMipCount=7

As you can see there are a large number of changes... the most interesting part of the section is probably these:

MinRequestedMipsToConsider=11
MinTimeToGuaranteeMinMipCount=0
MaxTimeToGuaranteeMinMipCount=0
UseTextureFileCache=TRUE
MaxTextureMipCount=13
MinTextureResidentMipCount=7

MinTextureResidentMipCount can not be changed... changing it below 7 will create a larger texture deficit, increasing it will get broken textures...

MinTimeToGuaranteeMinMipCount and MaxTimeToGuaranteeMinMipCount are what I think the game uses to release the "full picture" for you to see... The min 2 is there for low end hardwares... changing this below 2 could potentially increase load time and just overall slow down.

UseTextureFileCache seems to actually make the vid card ram/vram hold some texture information... I was able to completely remove texture pop-in between areas of the colesseum place (the one under dilmoor, I walked back and forth between the east/central sections)

Using these settings, I was able to reduce/eliminate texture pop-in for the majority of the game. There are still some when my vid card needs a total flush of memory ...

My Spec to run these smoothly + highest setting and shadow
Intel i7 920
GTX 285
3Gig Ram
Windows XP SP3
1920x1080 resolution

I don't have RushEngine.ini, but I have BaseEngine.ini and DefaultEngine.ini

Unfortunately, making ANY change to either file causes the game to say the .ini is broken when I start the .exe.
We're just a million little gods causing rain storms turnin' every good thing to rust.

This definately decreased pop-in, but at the same time it decreased the amount of mobs in the area as well . :( Whenever i enter a new area there are mobs but, if i initiate, and finish fighting one, the other mobs i saw before fighting dont appear on the field anymore.

Ah... sorry not tested throughly enough...
bUseBackgroundLevelStreaming=True (this must remain True) for the mobs to show up... this at the same time also increases texture pop in. To offset it a little more try the following:

[SystemSettings]
StaticDecals=TRUE
DynamicDecals=TRUE
DynamicLights=TRUE
DynamicShadows=TRUE
LightEnvironmentShadows=TRUE
CompositeDynamicLights=FALSE
ShadowFilterQualityBias=0
DirectionalLightMaps=TRUE
MotionBlur=TRUE
DepthOfField=TRUE
Bloom=TRUE
QualityBloom=TRUE
SpeedTreeLeaves=TRUE
SpeedTreeFronds=TRUE
OnlyStreamInTextures=FALSE
LensFlares=TRUE
FloatingPointRenderTargets=TRUE
Trilinear=TRUE
OneFrameGPULag=True
UseVSync=TRUE
SkeletalMeshLODBias=0
bEnableHighPolyChars=TRUE
ParticleLODBias=-1
DetailMode=2
ShadowFilterQualityBias=0
MaxAnisotropy=16
ScreenPercentage=100
SceneCaptureStreamingMultiplier=1.0
FoliageDrawRadiusMultiplier=1.0

Two interesting setting:
OnlyStreamInTextures=FALSE
OneFrameGPULag=True

The one frame GPU lag was Unreal 3's "fix" for streaming by withholding the mage in GPU... but apparently this game's loading screen is 1 frame short and thus shows the image before the texture applies...

[TextureStreaming]
PoolSize=158
HysteresisLimit=20
DropMipLevelsLimit=16
StopIncreasingLimit=12
StopStreamingLimit=7
MinFudgeFactor=0.5
FudgeFactorIncreaseRateOfChange=0.5
FudgeFactorDecreaseRateOfChange=-0.4
MinRequestedMipsToConsider=11
MinTimeToGuaranteeMinMipCount=0
MaxTimeToGuaranteeMinMipCount=0
UseTextureFileCache=FALSE
MaxTextureMipCount=11
MinTextureResidentMipCount=7

Some of the settings above are UT3's default setting and seem to work the best... I've tried mirror's edge and mass effect, both seems to be worse than UT3...

k, tested, and i can confirm that there are significantly less pop-in textures, and although textures do pop-in every now and then, its still better than the default config.

life is boring if ur azn.
all chinz ppl enjoy buffets.

best way to get "default" is just to delete the rushengine.ini
the game will make a default when you play it.
