I did that as well. It had no impact
ALAS!!! The op of this modifications is pretty right - many of the lines have multiple instances in the "BaseEngine", "BackupDefaultEngine" and "HawkenEngine" configs in my documents and game folders!!! I guess, that's the same 4 every1, too.
The search function (STRG-5) is really essential 2 find and modify 'em all. Did u check 4 doubles and triples, dude? If there's the slightest chance, u might have overseen any, i suggest u re-check all files again. i didn't notice that the 1st time i edited the files. Especially the "MipFade..."-lines have 3 instances, showing the same values!
I don't know if it works as intendet after all changes r finally done, but it's remarkable how many others stated 2 have great improvements after following the instructons exactly, so i believe this could be a real solution - provided it's done flawless. I will try out soon, and report back then.
