hey, your program does this : "[Display] fIBLFBloomRadius was removed due to it being an invalid setting (not recognized by the game)." it is in fact not invalid setting, it depends on the image based lens flare bloom system. The intensity of that effect is 0 by default, which is why you can't see the change to the bloom radius. If you want to test this yourself, go into the console and type in:"iblf intensity 3" to make the effect super obvious,"iblf anaintfar 0" to turn off the IBLF lens flare effect, but keep the bloom effect,"iblf bloomint 3" to turn on the bloom effect that is based on the IBLF"iblf bloomradius 7" to make the bloom spread out "iblf bloomradius 0" to see how it changes ini tweaks work the same way, using console just makes it quicker. edit: this is not to be confused with the bloom system that the game has via imagespaces, that is separate (although the bloom effect looks the same, the IBLF bloom is just another system on top of that, which is why the iblf bloomint is set to 0, its kind of redundant, but not an invalid setting)
