What effect does "bImageSpaceEffects=0" have in Creation Engine/Gamebryo games?

[seppesusi]

I disabled the setting in Fallout 3 to remove radial blur added by a mod. MSAA anti-aliasing was disabled (doesn't matter much since you can inject FXAA/SMAA or use SSAA) and the sepia-like filter in the quest "Tranquility Lane" was removed (which I personally prefer).

 

Can someone confirm that this variable doesn't introduce a significant graphical downgrade in some form? I'm mainly worried of reduced particle effects and god rays.

 

I assume that the withdrawal and addiction effects will change significantly, but they are so rare that it isn't worth worrying about. Depth of field and motion blur have always been disabled in my game for performance reasons.

This is just a guess ... but it implies to me that it turns off ImageSpaceModifiers being applied to ImageSpace's

 

Again I would suggest to study what an Image space is , then what,how,why an ImageSpaceModifer gets applied to it.

Which yes I failed to mention about game settings that would control these.

But it seemed you were specific in which Imods you wanted to change , and game settings would have a global consequence in adjustments. (most of the time I think anyways)

In Fallout 3, unless this was some compatibility issue with a third-party mod, the command hide the dialogue menus. May be due to transparency.

 

But as said in my other thread, the blur added by a mod can be disabled in its configuration menu.
